If you find that your files are missing after a Windows 10 upgrade, then this post will suggest a few ways, which can help you recover your lost files.
Files missing after Windows 10 upgrade or update
1] First of all, search for the files using Windows Search or any good third-party alternative Search Tool. Maybe the files have been relocated elsewhere.
2] Next, confirm that you are signed-in with your own profile and not with a temporary profile. To access your user files, you have to be signed in with your own username or an administrator account.
3] You may want to also check if your files are stuck in some disabled administrator account. Maybe after the upgrade, the files were moved to an admin account which may have now been disabled. To check this, type Computer Management is the taskbar search and open it. Click on System Tools > Local Users and Groups > Users.
Now see if you see any Administrator account which has an arrow pointing downwards. This means that the account has been disabled. Double-click on it open its Properties box and uncheck the Account is disabled check box. Click Apply/OK and exit.
Restart your computer, log in with this account and see if you can find the files.
4] If you have backups, restore them from the backups. If you don’t then see if you can retrieve the files from the Windows.old folder. You could also make use of the Data Recovery Tool from Microsoft.
5] There are other places you could see. If these folders exist on your system please see if the lost files are there:
- %SYSTEMDRIVE%\$INPLACE.~TR\Machine\Data\Documents and Settings\<User_Name>\
- %SYSTEMDRIVE%\$WINDOWS.~Q\Data\Documents and Settings\<User_Name>\
This is applicable in case your upgrade failed or in case of incomplete data migration. You will be required to show hidden and operating system files & folders.
6] In case you are unable to locate data, use an Administrator command prompt to perform a check on the entire drive for the missing data files. For instance to check for images, type the following commands one after the other:
dir *.jpg /a /s > %userprofile%\desktop\jpg-files.txt
Once the run is completed, you will see a jpg-files text file generated on your desktop, which will list all the jpg image files on your C drive.
If you can identify the location where the data has been copied, use drag and drop or robocopy.exe to help put the files in a more accessible location.
7] If you cannot locate any data files on the machine, check the \Windows\Panther\Setupact.log file and ensure that this was indeed an upgrade installation. If not, you can determine whether the partition was formatted in the log, as well as know to check other partitions for the data.
