You can easily restore a deleted file from the Trash by moving it from the Trash to another folder. Restored folders are automatically moved back to their original location. However, you will not be able to restore the item if you have emptied the Trash since deleting it - it has been permanently destroyed.
To restore an item from the Trash:
Click on the item that you want to restore in the Trash area on the bottom-right of the window.
If the item you have selected is a folder, the folder will be automatically returned to its original location. You are now finished with this procedure.
If the item you have selected is a file, click on the Move File link in the File operations area.
You are presented with a list of folders in the main display area. Navigate to the directory where you want to move the file. Open a folder by clicking on the folder icon.
When you have found the correct location, select the folder by clicking on the folder name link. The file or folder has now been moved to this location.
