By default the recycle bin is enabled on ClearOS shared folders. So don't panic when someone deletes one of your super important files.
Get started by going to the shared folder the file was deleted from. To access the ClearOS recycle bin, you will need to enable "Show hidden files and folders." If you haven't done so already, click Tools at the top of the window. Then click "Folder Options" select the View tap, then click the radio button next to "Show hidden files and folders." (If you use a Linux desktop, you only have to press Ctrl+h)
In the network share you will see the .trash folder, this is the recycle bin. The deleted files are organized by the username that deleted the file. To restore simply find and copy the file from here to where it belongs outside of the .trash folder.
