Windows 10: "Something went wrong and we couldn't add some files" error.

Hello, I am trying to use the default photos app to edit videos, but the editor has stopped working. I can no longer import new files longer than a minute or so and am greeted by the error in the title every time. I cannot add videos I had previously added either. I have tried repairing the photos app, resetting it, redownloading it several times, and performing a clean boot to ensure no conflicts were occuring and nothing is working. Any help would be much appreciated.

:)

 

"We couldn`t create a new partition or locate an existing one."

Same as over here:

Error message: "We couldn`t create a new partition or locate an existing one." | Windows 10 Forums

 

"We couldn`t create a new partition or locate an existing one."

Try this:

Before you get to that message, press SHIFT + F10 to open a command prompt.

Run diskpart.
At the diskpart prompt, run these commands:

list disk

At this point you should see the SSD as disk 0. If it has another disk number, use that number rather than "0" in the next command.

select disk 0
clean
exit (to exit from diskpart)
exit (to exit from the command prompt)





That should clear the contents of the disk. The entire disk space should then show up in Windows setup as "Unallocated Space" as in the screenshot below.
