You have asked this question 1, 2, 3, and 4 times and received answers and/or comments on three of those questions.
Asking the same thing multiple times is not necessarily likely to get you different answers. It's likely to get you the same answer multiple times.
Please pick one of these questions and continue the discussion in that one question. Please don't ask this a fifth time.

Ran in:
Well, does it? Check with Windows Explorer.
Rather than using sprintf (where you need to be careful which slashes you use) I would use fullfile to assemble the path from the individual pieces.
P1 = fullfile('c:', 'temp', 'foo.txt') % Note that MATLAB Answers code executes on Linux
P1 = 'c:/temp/foo.txt'
n = 42;
P2 = fullfile(tempdir, 'subdir1', 'subdir2', sprintf('X%d_file.txt', n))
P2 = '/tmp/subdir1/subdir2/X42_file.txt'
