Maintain files, apps and startup

Find large and duplicate files, delete to the Recycle Bin or permanently, uninstall apps, remove leftover entries and review startup in Hanki Maintain.

Maintain helps you find what takes up space and what starts with Windows, then clean up on your terms. Nothing is removed without your review.

What's in Maintain

Tab	Use it to
Files & storage	Inventory a folder or drive, see space by file type and list the Largest 100 files.
Apps & storage	Review installed apps and uninstall them with their own uninstaller.
Usage review	See optional observations of when apps were used.
Startup / undo	Review registry startup entries, disable supported ones and undo those changes.
Duplicates	Find files with identical contents in a folder.
Startup folders	Inspect shortcuts in your own and the machine-wide Startup folders.

Find large files

In Files & storage, choose a folder or drive and use Largest 100. Name and minimum-size filters narrow the list. Start with folders you know, such as Downloads or video exports: a large file may still be an important backup.

Find duplicates

In Duplicates, choose Find duplicates in folder… and read the coverage report. Hanki groups candidates by size and SHA-256, then rechecks the selected pair byte for byte before recycling. It never selects every extra copy for you; identical files in two places may both be needed.

Delete files

Move to Recycle Bin is the default. Restore a file from the Windows Recycle Bin.
Delete permanently asks you to confirm it can't be undone. Hanki never switches to permanent deletion by itself.
Some locations are refused on purpose.

Recycled files still take up space until you empty the Recycle Bin, and duplicate sizes are logical file sizes, not guaranteed savings.

Uninstall apps and leftover entries

Uninstalling runs the app's own uninstaller, the same one Windows Settings uses. For a leftover entry of an app that is already gone, Hanki saves a .reg backup in the app-entry-backups folder next to its saved data before removing it. Double-click that file to put the entry back. Every removal is listed in History → System actions.

Usage review can be incomplete and does not prove an app is unused.

Review startup

Identify the app and decide whether you need it at sign-in. Leave an unfamiliar entry alone until you know what it does.
Check the program path and whether the entry applies to you or to every user. Machine-wide changes may need administrator approval.
Disable one entry, then test your next sign-in.
Undo registry entries in Startup / undo, and Startup-folder changes in Recovery.

Disabling an entry doesn't uninstall the app, and these views cover the supported startup mechanisms, not every way software can start.
