I wrote a perfectly functional recover.c program yesterday.
But I can't get the file naming right. How can I add leading zeroes to the file name so the name is 000 instead of just 0?

Please consider leaving this question open if my edit is accepted because it will make sense, it has a good answer, and might help others.– ChrisuuCommented Jan 7, 2015 at 17:49

To print 000 you have to specify the format in the place holder.
for printing should be something like this:
printf("%03d", 0);
but to create a file with the name 000.jpg i think you need to use the function sprintf() wich can convert an integer to a string and then use this string to create the file.
sprintf(filename, "%03d.jpg", jpg_counter);
In this case the fist argument, filename, is where the resulting string is stored, you need to declare this string first. If the variable jpg_counter is 0 the resulting string in this case is filename = "000.jpg" the second argument is what you want to convert to a string. the third is tha variable you want to use for the placeholder.
