I backed up some folders from one PC and later tried to selectively restore a single small file to another PC. The restore function seemed (TRANSFERS display) to be looking at every single file inside all my backep up folder (taking hours!) rather than just restoring the file I wanted. What did I do wrong?
The best way to download a single file from BT Cloud would be via the BT Cloud website at https://btcloud.bt.com. You can find the file you're looking for by searching for it (if you know the file name), or by browsing your folder structure in the All My Files section of the website. Here you can select individual files, and then download them.
It is possible to do this using the desktop software too, but as you discovered the 'Restore' function is designed with people who are trying to restore all their PC files to a new device, so it's not the most efficient way of doing things.
