Fix 1: Check the Destination Drive Format
Are you attempting to copy a file to an external drive that uses a non-NTFS format? If so, you are likely to encounter such issues. For example, if the destination drive is formatted as FAT32, transferring a file larger than 4GB will most likely fail and result in an error.
Press Windows + E to open the File Explorer. Right-click on your drive and select Properties . Under General , check your drive’s file system.
If it says NTFS, disk format isn’t a problem, and you can continue with the solutions below. If it says FAT32, you may have to format the drive into the NTFS format.
Fix 2: Remove Write Protection for the Drive
Another reason you may have trouble copying files or folders to a storage drive is if it is write-protected. In that case, you must use the DiskPart utility to remove write protection from your drive.

Step 2: Type diskpart in the console and hit Enter .

Step 5: Paste the following command and press Enter to remove write protection for the selected device.

After completing the above steps, copy files and folders to that drive.
