do somebody have this file or what is that for?

I had to make this an answer, the comment has a character limit.

If your trying to manage your space reinstalling windows is the nuclear option. What you should really do is just to attempt to move non essential files like photos and videos to:

An external device, like a portable HDD

An SD card and have the card plugged in to the device permanently, and use it as an additional "drive"

Or use a cloud service like OneDrive, or Google Drive, or Dropbox <- this is the easier option, IMO.

There are also tools like CCleaner that can help reduce and manage space.

I found a few articles that you could use as a guide

If I've googled correctly this particular tab has about 32gb of space which isn't alot and will need management, so reinstalling the OS is only gonna work until the next time you run out of space.

All this can seem like work, but it's all best practice, if you move media to a removable device or to the cloud it's safer if your device ever fails.

If your still not getting the space your looking for here are steps to "Reset" windows

1. Go to "Settings" in start menu
2. Click "Update & security"
3. Click "Recovery"
4. Click "Get started"
5. And select "Remove everything"

Like I say, this is the nuclear option, but it is available to you.

Hope this helps, let me know if you need anything else.
