Multi Rule Dup Scanner

A lightweight Linux alternative to classic multi-rule duplicate finders
inspired by AllDup workflows. Independent open-source Linux project, not
affiliated with, sponsored by, or endorsed by Michael Thummerer Software
or Windows software vendors.

COMPOSABLE MULTI-RULE CRITERIA MATRIX
- Match ALL (AND) or ANY (OR) rules across folders with Include/Exclude regex
and Min/Max file size filters.
- Content Matching: SHA-256, MD5, or exact Byte-for-Byte verification after
fast partial pre-hashing.
- File & Metadata Rules: Same File Name (with Ignore Extension and
Case-Insensitive options), Same Extension, Same File Size, Modified Date
Tolerance (+/- seconds), Same Audio ID3 Artist+Title, and Same Image
Dimensions (W x H).
- Inside Archive Scanning: inspects entries inside .zip, .7z, .tar, .tar.gz,
.tar.bz2, .tar.xz, .tar.zst, and .rar archives.

GROUPED TREE RESULTS & SAFE DEDUPLICATION
- Collapsible duplicate group tree with smart selection rules: Keep Shortest
Name, Keep Longest Name, Keep Deepest/Shallowest Path, Keep Oldest/Newest,
and Mark All in Folder X.
- Real disk actions: Safe Backup Move, verified os.link Hardlink
Deduplication (same-device + byte-equality + inode verification), and
confirmed Delete, plus CSV export.

SAVED PROFILES & AUDIT LOG
- Save and reload named rule profiles in JSON and inspect persistent action
audit logs, with instant English / Vietnamese interface toggle.
