LARGE & DORMANT FILESSpace Hunter

Instant hunter for massive hidden space hogs & old archives.

The Large Files module is an ultra-fast hunter for the heaviest files occupying your storage. Within milliseconds, DiskUni indexes millions of files and organizes them into high-impact size thresholds (>100 MB, >1 GB, >10 GB, >50 GB). It cross-references file sizes with last accessed timestamps, helping you immediately discover forgotten 4K video exports, dormant virtual disk images, and massive archive packages.

06 / FREQUENTLY ASKED QUESTIONS

Can I filter large files by their last modified or opened date?

Yes! DiskUni allows you to filter large files by both size thresholds and dormancy (e.g., files larger than 5 GB not opened in the last 180 days).

Does it help locate hidden Docker and WSL2 virtual disks?

Absolutely. DiskUni specifically highlights `.vhdx`, `.vmdk`, and `ext4.vhdx` containers that typically hide deep in `%LOCALAPPDATA%`.

Can I move large files to an external drive instead of deleting them?

Yes. DiskUni includes a 1-click 'Transfer to External Volume' command with checksum verification.
