Changelog

Added

  • Per-file selection checkboxes inside each duplicate group card with "Delete X selected" button for manual precise cleanup
  • Stop button in the bulk-delete progress overlay to halt the operation between batches
  • Conflict resolution modal (Rule 4): when the largest unprotected file is bigger than the largest protected file, the group is skipped and a resolution dialog is shown at the end

Changed

  • Rule 1 (all-unprotected groups): now keeps the LARGEST file and deletes the rest, instead of deleting all
  • Rule 3 ("Delete all but one protected copy" opt-in): now keeps the single LARGEST protected file and deletes everything else
  • Bulk delete now processes one group per HTTP request (batch size 1) to stay within proxy timeout limits
  • Duplicate files are permanently deleted, bypassing the Nextcloud trash bin — prevents multi-minute copy-to-trash operations that caused timeouts for large video files

Fixed

  • Bulk delete no longer fails or times out on large video files: trash bin copy step is bypassed, enabling fast permanent deletion
  • Cloudflare 524 timeout errors eliminated for large video group deletes
  • HTTP 500 errors on video deletes caused by failed trash-bin move operations are resolved
  • Bulk delete operation no longer aborts on a single failed batch; failures are logged and skipped gracefully

Changelog

Added

  • Hash cache: perceptual hashes are stored in the database after the first scan and reused on subsequent runs — only new or changed files are re-hashed, making re-scans of large libraries (400 GB+) dramatically faster
  • BK-tree comparison: replaced the O(n^2) pairwise hash comparison with an O(n log n) BK-tree nearest-neighbour search, reducing the grouping phase from hours to seconds for large libraries

Fixed

  • HEIC/HEIF photos (iPhone) now supported via pillow-heif — previously skipped silently
  • Very large images (>89 MP) no longer crash the scanner (PIL decompression bomb limit raised to 300 MP)
  • Scan completion notification now uses the internal container URL instead of the external Cloudflare domain, fixing broken notifications

Changelog

Added

  • Per-file selection checkboxes inside each duplicate group card with "Delete X selected" button for manual precise cleanup
  • Stop button in the bulk-delete progress overlay to halt the operation between batches
  • Conflict resolution modal (Rule 4): when the largest unprotected file is bigger than the largest protected file, the group is skipped and a resolution dialog is shown at the end

Changed

  • Rule 1 (all-unprotected groups): now keeps the LARGEST file and deletes the rest, instead of deleting all
  • Rule 3 ("Delete all but one protected copy" opt-in): now keeps the single LARGEST protected file and deletes everything else
  • Bulk delete now processes one group per HTTP request (batch size 1) to stay within proxy timeout limits
  • Duplicate files are permanently deleted, bypassing the Nextcloud trash bin — prevents multi-minute copy-to-trash operations that caused timeouts for large video files

Fixed

  • Bulk delete no longer fails or times out on large video files: trash bin copy step is bypassed, enabling fast permanent deletion
  • Cloudflare 524 timeout errors eliminated for large video group deletes
  • HTTP 500 errors on video deletes caused by failed trash-bin move operations are resolved
  • Bulk delete operation no longer aborts on a single failed batch; failures are logged and skipped gracefully

Changelog

Added

  • Hash cache: perceptual hashes are stored in the database after the first scan and reused on subsequent runs — only new or changed files are re-hashed, making re-scans of large libraries (400 GB+) dramatically faster
  • BK-tree comparison: replaced the O(n^2) pairwise hash comparison with an O(n log n) BK-tree nearest-neighbour search, reducing the grouping phase from hours to seconds for large libraries

Fixed

  • HEIC/HEIF photos (iPhone) now supported via pillow-heif — previously skipped silently
  • Very large images (>89 MP) no longer crash the scanner (PIL decompression bomb limit raised to 300 MP)
  • Scan completion notification now uses the internal container URL instead of the external Cloudflare domain, fixing broken notifications

Changelog

Added

  • Per-file selection checkboxes inside each duplicate group card with "Delete X selected" button for manual precise cleanup
  • Stop button in the bulk-delete progress overlay to halt the operation between batches
  • Conflict resolution modal (Rule 4): when the largest unprotected file is bigger than the largest protected file, the group is skipped and a resolution dialog is shown at the end

Changed

  • Rule 1 (all-unprotected groups): now keeps the LARGEST file and deletes the rest, instead of deleting all
  • Rule 3 ("Delete all but one protected copy" opt-in): now keeps the single LARGEST protected file and deletes everything else
  • Bulk delete now processes one group per HTTP request (batch size 1) to stay within proxy timeout limits
  • Duplicate files are permanently deleted, bypassing the Nextcloud trash bin — prevents multi-minute copy-to-trash operations that caused timeouts for large video files

Fixed

  • Bulk delete no longer fails or times out on large video files: trash bin copy step is bypassed, enabling fast permanent deletion
  • Cloudflare 524 timeout errors eliminated for large video group deletes
  • HTTP 500 errors on video deletes caused by failed trash-bin move operations are resolved
  • Bulk delete operation no longer aborts on a single failed batch; failures are logged and skipped gracefully

Changelog

Added

  • Hash cache: perceptual hashes are stored in the database after the first scan and reused on subsequent runs — only new or changed files are re-hashed, making re-scans of large libraries (400 GB+) dramatically faster
  • BK-tree comparison: replaced the O(n^2) pairwise hash comparison with an O(n log n) BK-tree nearest-neighbour search, reducing the grouping phase from hours to seconds for large libraries

Fixed

  • HEIC/HEIF photos (iPhone) now supported via pillow-heif — previously skipped silently
  • Very large images (>89 MP) no longer crash the scanner (PIL decompression bomb limit raised to 300 MP)
  • Scan completion notification now uses the internal container URL instead of the external Cloudflare domain, fixing broken notifications

Changelog

Added

  • Per-file selection checkboxes inside each duplicate group card with "Delete X selected" button for manual precise cleanup
  • Stop button in the bulk-delete progress overlay to halt the operation between batches
  • Conflict resolution modal (Rule 4): when the largest unprotected file is bigger than the largest protected file, the group is skipped and a resolution dialog is shown at the end

Changed

  • Rule 1 (all-unprotected groups): now keeps the LARGEST file and deletes the rest, instead of deleting all
  • Rule 3 ("Delete all but one protected copy" opt-in): now keeps the single LARGEST protected file and deletes everything else
  • Bulk delete now processes one group per HTTP request (batch size 1) to stay within proxy timeout limits
  • Duplicate files are permanently deleted, bypassing the Nextcloud trash bin — prevents multi-minute copy-to-trash operations that caused timeouts for large video files

Fixed

  • Bulk delete no longer fails or times out on large video files: trash bin copy step is bypassed, enabling fast permanent deletion
  • Cloudflare 524 timeout errors eliminated for large video group deletes
  • HTTP 500 errors on video deletes caused by failed trash-bin move operations are resolved
  • Bulk delete operation no longer aborts on a single failed batch; failures are logged and skipped gracefully

Changelog

Added

  • Hash cache: perceptual hashes are stored in the database after the first scan and reused on subsequent runs — only new or changed files are re-hashed, making re-scans of large libraries (400 GB+) dramatically faster
  • BK-tree comparison: replaced the O(n^2) pairwise hash comparison with an O(n log n) BK-tree nearest-neighbour search, reducing the grouping phase from hours to seconds for large libraries

Fixed

  • HEIC/HEIF photos (iPhone) now supported via pillow-heif — previously skipped silently
  • Very large images (>89 MP) no longer crash the scanner (PIL decompression bomb limit raised to 300 MP)
  • Scan completion notification now uses the internal container URL instead of the external Cloudflare domain, fixing broken notifications

Changelog

Added

  • Per-file selection checkboxes inside each duplicate group card with "Delete X selected" button for manual precise cleanup
  • Stop button in the bulk-delete progress overlay to halt the operation between batches
  • Conflict resolution modal (Rule 4): when the largest unprotected file is bigger than the largest protected file, the group is skipped and a resolution dialog is shown at the end

Changed

  • Rule 1 (all-unprotected groups): now keeps the LARGEST file and deletes the rest, instead of deleting all
  • Rule 3 ("Delete all but one protected copy" opt-in): now keeps the single LARGEST protected file and deletes everything else
  • Bulk delete now processes one group per HTTP request (batch size 1) to stay within proxy timeout limits
  • Duplicate files are permanently deleted, bypassing the Nextcloud trash bin — prevents multi-minute copy-to-trash operations that caused timeouts for large video files

Fixed

  • Bulk delete no longer fails or times out on large video files: trash bin copy step is bypassed, enabling fast permanent deletion
  • Cloudflare 524 timeout errors eliminated for large video group deletes
  • HTTP 500 errors on video deletes caused by failed trash-bin move operations are resolved
  • Bulk delete operation no longer aborts on a single failed batch; failures are logged and skipped gracefully

Changelog

Added

  • Hash cache: perceptual hashes are stored in the database after the first scan and reused on subsequent runs — only new or changed files are re-hashed, making re-scans of large libraries (400 GB+) dramatically faster
  • BK-tree comparison: replaced the O(n^2) pairwise hash comparison with an O(n log n) BK-tree nearest-neighbour search, reducing the grouping phase from hours to seconds for large libraries

Fixed

  • HEIC/HEIF photos (iPhone) now supported via pillow-heif — previously skipped silently
  • Very large images (>89 MP) no longer crash the scanner (PIL decompression bomb limit raised to 300 MP)
  • Scan completion notification now uses the internal container URL instead of the external Cloudflare domain, fixing broken notifications

Changelog

Added

  • Per-file selection checkboxes inside each duplicate group card with "Delete X selected" button for manual precise cleanup
  • Stop button in the bulk-delete progress overlay to halt the operation between batches
  • Conflict resolution modal (Rule 4): when the largest unprotected file is bigger than the largest protected file, the group is skipped and a resolution dialog is shown at the end

Changed

  • Rule 1 (all-unprotected groups): now keeps the LARGEST file and deletes the rest, instead of deleting all
  • Rule 3 ("Delete all but one protected copy" opt-in): now keeps the single LARGEST protected file and deletes everything else
  • Bulk delete now processes one group per HTTP request (batch size 1) to stay within proxy timeout limits
  • Duplicate files are permanently deleted, bypassing the Nextcloud trash bin — prevents multi-minute copy-to-trash operations that caused timeouts for large video files

Fixed

  • Bulk delete no longer fails or times out on large video files: trash bin copy step is bypassed, enabling fast permanent deletion
  • Cloudflare 524 timeout errors eliminated for large video group deletes
  • HTTP 500 errors on video deletes caused by failed trash-bin move operations are resolved
  • Bulk delete operation no longer aborts on a single failed batch; failures are logged and skipped gracefully

Changelog

Added

  • Hash cache: perceptual hashes are stored in the database after the first scan and reused on subsequent runs — only new or changed files are re-hashed, making re-scans of large libraries (400 GB+) dramatically faster
  • BK-tree comparison: replaced the O(n^2) pairwise hash comparison with an O(n log n) BK-tree nearest-neighbour search, reducing the grouping phase from hours to seconds for large libraries

Fixed

  • HEIC/HEIF photos (iPhone) now supported via pillow-heif — previously skipped silently
  • Very large images (>89 MP) no longer crash the scanner (PIL decompression bomb limit raised to 300 MP)
  • Scan completion notification now uses the internal container URL instead of the external Cloudflare domain, fixing broken notifications

Changelog

Added

  • Per-file selection checkboxes inside each duplicate group card with "Delete X selected" button for manual precise cleanup
  • Stop button in the bulk-delete progress overlay to halt the operation between batches
  • Conflict resolution modal (Rule 4): when the largest unprotected file is bigger than the largest protected file, the group is skipped and a resolution dialog is shown at the end

Changed

  • Rule 1 (all-unprotected groups): now keeps the LARGEST file and deletes the rest, instead of deleting all
  • Rule 3 ("Delete all but one protected copy" opt-in): now keeps the single LARGEST protected file and deletes everything else
  • Bulk delete now processes one group per HTTP request (batch size 1) to stay within proxy timeout limits
  • Duplicate files are permanently deleted, bypassing the Nextcloud trash bin — prevents multi-minute copy-to-trash operations that caused timeouts for large video files

Fixed

  • Bulk delete no longer fails or times out on large video files: trash bin copy step is bypassed, enabling fast permanent deletion
  • Cloudflare 524 timeout errors eliminated for large video group deletes
  • HTTP 500 errors on video deletes caused by failed trash-bin move operations are resolved
  • Bulk delete operation no longer aborts on a single failed batch; failures are logged and skipped gracefully

Changelog

Added

  • Hash cache: perceptual hashes are stored in the database after the first scan and reused on subsequent runs — only new or changed files are re-hashed, making re-scans of large libraries (400 GB+) dramatically faster
  • BK-tree comparison: replaced the O(n^2) pairwise hash comparison with an O(n log n) BK-tree nearest-neighbour search, reducing the grouping phase from hours to seconds for large libraries

Fixed

  • HEIC/HEIF photos (iPhone) now supported via pillow-heif — previously skipped silently
  • Very large images (>89 MP) no longer crash the scanner (PIL decompression bomb limit raised to 300 MP)
  • Scan completion notification now uses the internal container URL instead of the external Cloudflare domain, fixing broken notifications

Changelog

Added

  • Per-file selection checkboxes inside each duplicate group card with "Delete X selected" button for manual precise cleanup
  • Stop button in the bulk-delete progress overlay to halt the operation between batches
  • Conflict resolution modal (Rule 4): when the largest unprotected file is bigger than the largest protected file, the group is skipped and a resolution dialog is shown at the end

Changed

  • Rule 1 (all-unprotected groups): now keeps the LARGEST file and deletes the rest, instead of deleting all
  • Rule 3 ("Delete all but one protected copy" opt-in): now keeps the single LARGEST protected file and deletes everything else
  • Bulk delete now processes one group per HTTP request (batch size 1) to stay within proxy timeout limits
  • Duplicate files are permanently deleted, bypassing the Nextcloud trash bin — prevents multi-minute copy-to-trash operations that caused timeouts for large video files

Fixed

  • Bulk delete no longer fails or times out on large video files: trash bin copy step is bypassed, enabling fast permanent deletion
  • Cloudflare 524 timeout errors eliminated for large video group deletes
  • HTTP 500 errors on video deletes caused by failed trash-bin move operations are resolved
  • Bulk delete operation no longer aborts on a single failed batch; failures are logged and skipped gracefully

Changelog

Added

  • Hash cache: perceptual hashes are stored in the database after the first scan and reused on subsequent runs — only new or changed files are re-hashed, making re-scans of large libraries (400 GB+) dramatically faster
  • BK-tree comparison: replaced the O(n^2) pairwise hash comparison with an O(n log n) BK-tree nearest-neighbour search, reducing the grouping phase from hours to seconds for large libraries

Fixed

  • HEIC/HEIF photos (iPhone) now supported via pillow-heif — previously skipped silently
  • Very large images (>89 MP) no longer crash the scanner (PIL decompression bomb limit raised to 300 MP)
  • Scan completion notification now uses the internal container URL instead of the external Cloudflare domain, fixing broken notifications

Changelog

Added

  • Per-file selection checkboxes inside each duplicate group card with "Delete X selected" button for manual precise cleanup
  • Stop button in the bulk-delete progress overlay to halt the operation between batches
  • Conflict resolution modal (Rule 4): when the largest unprotected file is bigger than the largest protected file, the group is skipped and a resolution dialog is shown at the end

Changed

  • Rule 1 (all-unprotected groups): now keeps the LARGEST file and deletes the rest, instead of deleting all
  • Rule 3 ("Delete all but one protected copy" opt-in): now keeps the single LARGEST protected file and deletes everything else
  • Bulk delete now processes one group per HTTP request (batch size 1) to stay within proxy timeout limits
  • Duplicate files are permanently deleted, bypassing the Nextcloud trash bin — prevents multi-minute copy-to-trash operations that caused timeouts for large video files

Fixed

  • Bulk delete no longer fails or times out on large video files: trash bin copy step is bypassed, enabling fast permanent deletion
  • Cloudflare 524 timeout errors eliminated for large video group deletes
  • HTTP 500 errors on video deletes caused by failed trash-bin move operations are resolved
  • Bulk delete operation no longer aborts on a single failed batch; failures are logged and skipped gracefully

Changelog

Added

  • Hash cache: perceptual hashes are stored in the database after the first scan and reused on subsequent runs — only new or changed files are re-hashed, making re-scans of large libraries (400 GB+) dramatically faster
  • BK-tree comparison: replaced the O(n^2) pairwise hash comparison with an O(n log n) BK-tree nearest-neighbour search, reducing the grouping phase from hours to seconds for large libraries

Fixed

  • HEIC/HEIF photos (iPhone) now supported via pillow-heif — previously skipped silently
  • Very large images (>89 MP) no longer crash the scanner (PIL decompression bomb limit raised to 300 MP)
  • Scan completion notification now uses the internal container URL instead of the external Cloudflare domain, fixing broken notifications
