When you try to copy a file from a location, the calculated destination path is the sum of the characters that exist in the source path and the file name. Windows has a limit on the number of characters that is applied by default to a file path, which is normally 260.
Some Windows 10 users experience the “Destination path too long” error when moving or copying files from their original location to another folder or drive.
