You should use os.path.exists to test if a file exists. Your
exception-catching structure is not necessary.
Also, if the file you are reading from contains proper Windows
filenames, it is not necessary to replace \ with \\ and so forth. The
\ acts as an escape character only when it is in Python source code,
not when it is in a string read from the real world.
Also, because you wisely use "for x in inputfiles:" it is not necessary
to search for and replace newlines.
