Hi emizhang-msft
Yes I did in fact find the missing folders ( all 150 of them) and I was able to restore them thank you... Never the less the fact remains that they were not deleted, nor were they moved and there's nothing in the transaction history to say how they ended up there...? It's left me feeling that I can't trust the software, not to mention the fact that the reinstated folders and files leave me with the same job I had already finished.... The additional problem has occurred because I couldn't find a way to just restore the missing folders/files and instead I had to restore all the work I had already done (not related to the missing folders....)? Perhaps I missed something and the restoration was the result of me not knowing the software well enough?
Anyway thank you for your help, much appreciated
Kind regards
Chris Lster
