Unfortunately network share deletes are not diverted to the recycle bin.
you could check Undelete Plus on the server from where you started the copy.
Any tool that can do the following will work -- but, only while the data is really around in the deleted area.
Accidentally deleting a file from your computer, flash disk, camera, or the like does not mean it is lost forever. Software doesn’t destroy files when it deletes, it simply marks the space the file was using as being available for re-use. If nothing has needed that space since the deletion, the data is still there and the file can be recovered.
UndeletePlus is powerful software that can quickly scan a computer or storage medium for deleted files and restore them on command. It works with computers, flash drives, cameras, and other forms of data storage. Simply scan the device, select the files you want to recover, and click a button to restore the information or picture you thought was lost forever.
