Frequently asked questions
Does DiskTreeSize automatically clean caches?
No. It shows the space used by files and folders without deciding which files are safe to remove. Moving an item to Trash requires your action and a separate confirmation.
Can I filter files larger than 1 GB?
The current version has no file-size range filter. To find large files, sort by size and expand folders. The search field matches file and folder names only.
Why does the result differ from Storage in System Settings?
DiskTreeSize measures the selected, accessible folder. System Settings covers the disk and uses its own categories. Protected or inaccessible locations can be skipped, so the totals need not match.
Does moving a file to Trash immediately free the displayed space?
Not necessarily. Trashed files remain on disk and can be restored before the Trash is emptied. Allocated size is not a promise of recoverable space. Empty the Trash only after deciding you no longer need its contents.
