File.Move wont work , error. IOException: Win32 IO returned ERROR_ALREADY_EXISTS. Path:

i’m using File.Move to move a text file to Application.dataPath
File.Delete works just fine but not File.Move

				File.Move(("My File Path of file "),Application.dataPath);

what could be the problem ?

The exception is telling you that the file already exists. From the File.Move doc:

You cannot use the Move method to overwrite an existing file.

You’ll have to delete or rename the file if it already exists before you try to move it.
