First and foremost, MAKE BACKUPS of all those files. To a DVD, other hard drive, flash drive, etc. Losing them is not an option.
If the files are being save in the "OneDrive" cloud, try creating a local login profile instead of the Microsoft email login version you're using now. Once there, copy all your files to the new profile, which will reside on the computer's hard drive, in the "Documents" folder.
Here, using a local login on all our Win10 computers, we have never seen files simply disappear from the "My Documents" folder.
Hope this helps.
I meticulously store information in Documents and always have - using Windows XP, Vista, Windows 8 and now Windows 10. I have folders dedicated to Taxes, Birth Certificates, etc., etc., containing valuable information - nothing new there - everyone does BUT........ Windows 10 has taken to leaving me named folders but when I click to open there is nothing in there - not a file in sight.
I don't know when this happens or why. I posted on a Windows Forum and was prompted to right click on the folder and select Restore Previous Version. I tried this and was given a selection of 4 or 5 previous versions. After selecting three or four or more I was eventually able to find the missing file. BUT there are two "howevers" - the first being that the task that night was humungous, having to go through all my documents and the folders therein and then my husband's and then general shared folders. The second "however" is that - they have gone again!!!!!! I have many many folders in Documents with no files within.
What is going on?
I would be very grateful for a solution to this problem.
