Hi Prema,
Are using any tool to get the information "windows directory, it shows file repository and the folder is 100%"?
If you are trying to create more space in the compute. I would suggest to optimize your computer and check if it helps.
Optimize Windows for better performance
Note:
**1)**Disk cleanup cleans up files associated with your user account. You can also use Disk Cleanup to clean up all the files on your computer.
2) Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.
The driver store is a trusted location of inbox and third-party driver packages. This means that before a driver can be installed it must first be injected into the driver store, this process is called staging. The driver store is located under C:\Windows\System32\DriverStore\FileRepository. Windows keeps a copy of every driver you install in a place called the Driver Store. It is located in “C:\Windows\System32\DriverStore\FileRepository”.
Note: It is not suggested to delete drivers from the folder as deleting an incorrect driver might lead to instability and issues within PC.
Hope this information helps. Reply to the post with updated status of the issue to assist you further.
