ダウンロードやバックアップに潜む重複ファイルを削除
ファイルのコピーはディスク容量の無駄遣いです。VantarisProは正確なハッシュ計算によって本物の重複ファイルを特定し、安心して削除できるようにします。
Why “size” is duplicated across folders
Users copy “final” and “final2” folders, cloud sync duplicates offline copies, and installers pile up in Downloads. Explorer size alone never shows duplication.
Hash-aware dedupe
Duplicate Finder finds redundant copies, Disk Space Explorer shows dominant folders, Drive Cleaner removes reviewable junk categories, and File Shredder handles sensitive duplicates when deletion must be final.

Questions about this topic
Are similar photos detected?
Byte-identical hashing differs from visual similarity—use media tools for near-duplicates.
Will symlinks confuse scans?
Symlinks and junctions need careful handling—follow module guidance for your layout.
Can I scan network drives?
Yes when paths are reachable—expect latency and permission constraints.
Does dedupe break hard links?
Review before deleting—hard-linked files share inode-equivalent references on NTFS.
