Which statement is true about version control of files that are transferred between a Windows laptop and a Windows desktop PC?
Windows does not allow files with the same name to exist in the same folder.
In order to make a copy of a file on the laptop, you select the file and choose Cut.
If the files have the same name, but one is newer than the other, the new file will automatically overwrite the older file.
If the files are exactly the same and have the same modification dates, Windows will not prompt you about replacing the file.
