How can I restore my deleted files?

You can do that by navigating to the Deleted files in the Main menu, selecting the correct files and clicking on Undelete in the upper right-hand corner. OR if you right-click on the file and click the Undelete button that appears. To select multiple files/folders check the checkboxes on the left side of files/folders. You can also quickly select multiple files/folders by holding down the Shift key and clicking on the first and the last file/folder of the files/folders you want to undelete. When files/folders are selected, click the Undelete button.

You can restore your files within 7 days of deletion if you have the free Koofr account and within 30 days of deletion if you have the paid Koofr account. After the retention period is over your files will be permanently deleted from your Koofr account and you can no longer restore them.
