How to restore images transferred to folder using turbo network storage?

The images that I transferred to a new folder in my turbo network-attached storage did not update and were removed when I quit the application. The times when I attempted to re-launch the folder, the system prompted me to start over, but the images were still not saved in the folder. Is there a function in this application to restore the images that were lost during the transfer since I believe the data is backed up in a main folder?
