The Network Recycle Bin keeps the deleted files on the NAS. Within each shared folder, a dedicated folder by the name @Recycle is created after this feature is enabled. Specify the number of days (1-180) to keep the deleted files and older files deleted will be deleted first. You may also specify the file extensions to be excluded from the bin. Click “Apply” and the NAS will create a shared folder “Network Recycle Bin” automatically.
Note that this feature only supports file deletion via Samba, AFP and QNAP File Station.
