Full Disk Access is optional for many diCleaner workflows. You can keep it disabled and grant access to individual folders when a tool needs them.
What can still work
Supported tools can analyze locations macOS already allows the app to read. Depending on the edition and folder authorization, this can include selected personal folders, external disks, Downloads, and other user-chosen locations.
File analysis, application inventory, and cleanup can still provide useful results within that accessible scope.
What may be incomplete
Protected system logs, some Trash locations, application containers, and related files can be skipped. A total based on accessible files should not be interpreted as the total contents of the Mac.
The affected tool may display an access notice, omit a category, return a smaller result, or appear empty when its primary location is protected.
Work with limited access
- Select a narrow folder you want to inspect.
- Grant folder access when prompted.
- Run the scan.
- Read any skipped-location or permission messages.
- Review and act only on the result shown.
If you later enable Full Disk Access, quit and reopen diCleaner and start a new scan. The old result does not become complete automatically.
Keep access disabled
Leave Full Disk Access off when you do not need protected locations or prefer the narrower permission model. You can enable it for a specific task and revoke it afterward.
Revoking it does not delete files, undo previous cleanup, or remove saved folder authorizations.
