Does a scan change my files?
Scanning reads supported metadata and file information. A change occurs only after you choose an action and confirm it.
Is every result safe to delete?
No. Results are candidates organized by a tool’s purpose. Personal files, shared app data, offline caches, logs needed for diagnosis, and active update data can still be valuable.
Why are some items selected?
A tool can preselect categories it is designed to handle, but the final decision remains yours. Expand groups and deselect anything you want to preserve.
Should I remove the maximum possible amount?
No. Storage reclaimed is not a quality score. Remove data you understand and no longer need.
Can caches be recreated?
Many can, but recreation may require time, bandwidth, account access, or the original service. Some folders called “cache” by users can also contain offline or recovery data, so rely on the supported category and inspect unfamiliar entries.
Does diCleaner replace a backup?
No. Maintain independent backups and confirm that they complete successfully.
Can uninstalling an app remove documents?
Related-file searches can find support data and other associated paths. Review them carefully and preserve user documents, projects, presets, and data shared with another app.
Is Full Disk Access required?
Not for every tool. Without it, protected locations can be skipped. Enable it only when those locations are relevant.
Are local scan files uploaded?
Local scanning does not upload file contents. Online Information & Comments is a separate optional service and can show the item details it proposes to send.
What should I do when uncertain?
Deselect the item, open it in Finder, identify the owning app, and leave it in place until you can make an informed decision.
