Hello, thank you for reaching out to Microsoft Q&A.
May I please know if you are using a personal or work computer?
If it is a personal device, could you please let me know which folder or drive you are copying the files to?
If you have a local disk drive D: in addition to the system drive, please try copying the files there. Here’s what you can try:
- Disconnect your mobile device from your computer (both USB and Bluetooth).
- Open Command Prompt as an administrator, then run the command below:
sfc /scannow
- Once the scan is complete, restart your computer.
- Plug the mobile device back in via USB. (Give the transfer permissions on your Mobile device)
- On your local disk drive, create a new folder.
- Copy the files from your mobile device and paste them into the new folder.
If you are still having issues, please share a screenshot of the error message here.
