See the big picture

Bigger blocks mean bigger files. Understand your storage without opening folder after folder.

Find what matters

Search through folders and compare file sizes to find the downloads and projects worth a second look.

Stay in control

Preview your files, review your choices, and decide what moves to the Trash.

From “disk full” to
“there it is.”

That old project archive. The video you forgot about. Search across subfolders and see exactly how much space each file takes up.

A visual map and a familiar file list, working together.

Search across folders. See the space behind each result.

Keep what matters.
Review extra copies.

At least one copy stays. You make the final choice.

Disklio’s duplicate finder groups identical files and offers controls to keep a copy and review selected duplicates.
Compare identical files before deciding what to remove.

It stays that way.
