Does Cleanmgr Delete Important Files?

It depends on the user. You determine specific categories for cleanup and confirm the deletion. Cleanmgr permanently removes the files within those categories from your hard drive. Before cleanup, review the categories and to-be deleted files to ensure you don’t unintentionally remove any critical data.

For concerns about specific files or categories, back up your data or use alternative data management methods, such as manually deleting files or using specialized tools. Note that Cleanmgr deletes files that are safe to remove and are not mandatory for the functioning of your operating system or applications.
