Hello @lucy_8860,

Would you mind providing some details about the circumstances under which these files were saved or edited and the location of the files where they were stored?

Also, kindly share a link to a sample file after uploading to Dropbox/Google Drive/etc. so we can check it on our end. Although we cannot guarantee a successful recovery, we will try our best to do so.

Looking forward to hearing from you.
