There are n JPEG files, with file names f1, f2, ..., fn. I want to change their names to, for example, g1, g2, ..., gn. Of course the easiest way is to change file names by myself, but this is not convenient when n is large. How should I do by using Mathematica? I tried: Export["g1.jpg", Import["f1.jpg", "JPEG"], "JPEG"] It does change the file name as I expect. There is, however, a side effect: somehow the file size in bytes of g1.jpg is one-tenth of that of f1.jpg. Besides, I have to read in the files and then write out the files -- I don't think these two steps are really necessary, because all I want to do is to change the file names. Is there any better method? Thank you in advance.
