Duplicate File Finder allows you to move duplicate files to the Trash by default. However, you might not have permission to do that. This may happen in the following cases:
- The file is being used by another program.
- You don’t have the necessary user account permission to remove it. To get the permission switch to Finder, select the file and use “Get info” command from the context menu or using Cmd+I key shortcut. Change the file permission in the Sharing & Permissions category.
If you are scanning an external storage, then the reasons for the message might be:
- Your external drive does not have a Trash bin yet. A Trash bin for external storage is created when you remove a file via Finder. So to resolve this issue you should remove any one file on external storage in Finder.
- Your disk is connected to your external storage as a read-only. This could happen, for example, if you have connected your disk with NTFS and don’t have a driver to write to NTFS. You should therefore install the necessary extension to allow removal of the duplicates. Read more >>
