⚠️ Read Before You Delete

DupeDoc moves deleted files to a DupeDoc_Trash folder in your home directory — not your system recycle bin. Once you empty that folder, those files are permanently gone. DupeDoc is built for fast decisions. Take a breath before you empty the trash. We are not responsible for permanently deleted files. There is no undo beyond the trash folder.
