Windows 10: I cannot back up: "file history does not recognize this file"

In the advance settings, I have the following message: "file history does not recognize this file". Then I go to "select another drive" and select it again and get message "file history drive is disconnected". The drive is connected and works fine.

File History Physical Connected But Not Electronic

Hello Candun,

Thank you for posting your concern in Microsoft Community and welcome to the Windows 10 Family.

From the description provided, I understand that File History is not recognizing the external USB expansion drive, even though the drive had worked initially and it was behaving normally in File Explorer.

This issue may occur if any of the backup in the drive you are backing up is corrupted or the library is corrupted.

Please follow the below suggested methods and check if it helps to resolve the issue.

Method 1

1. Open File History and click Select Drive. Select a different drive other than the one that is failing to be recognized. you can consider adding an extra internal HDD to your PC in this situation.

2. Go to the external USB drive that wasn't being recognised, find the File History folder and rename it to "File History.old" or delete it.

3. Go to your C:\Users\your user folder\AppData\Local\Microsoft\Windows, find the File History folder and rename it "File History.old" or delete it.

4. Re-open File History, click Select drive and select the original USB drive that was not being recognised. The drive should now set up normally and start operating.

5. Delete the File History folder on the drive used in step 1

Method 2

This issue may happen due to system file corruption. I suggest you to run System file checker. System File checker (SFC) scan is done to check if there are any corrupted system files that could be causing this issue. Kindly follow
the below given steps:

• 
  Press Windows key + X, select
  Command prompt (Admin) to bring up elevated Command prompt.
  
• 
  In Command prompt type
  sfc/scannow and press enter.
  

• Restart the computer.

If no corrupted system files were found in the previous state, then I suggest you to try the following steps to employ the DISM command lines:

• 
  Open command prompt by pressing Windows key + X and selecting “Command prompt admin”.
  
• 
  In command prompt, type the following commands and press Enter after each command:
  

DISM.exe /Online /Cleanup-image /Scanhealth

DISM.exe /Online /Cleanup-image /Restorehealth

• 
  Close the command prompt and restart the PC and check if it works.

File History not backing up any files

Hello Victor

Thank you for the response. I had already checked that thread, but it hasn't helped me:

• The thread deals with Windows 8's implementation of File History, which is somewhat different to that of Windows 10.
• Most of the thread deals with setting up File History (which I have already done, precisely following the recommended steps). The third link in the thread might have been useful since it appears to link to a page that deals with troubleshooting File History
  (as opposed to setting it up), but unfortunately the link is dead.

Any further suggestions would be greatly appreciated.
