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?
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
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.
