In a windows (98,XP,VISTA) OS, is there a simple procedure to create a macro to rename files by adding a string of character(s) at the beginning (or end) of each existing filename within a folder? I often run into repetitive tasks on my computer(s), for example; renaming files within a folder in a sequence. I have a folder with 120 songs in it and don't want the OS manager to sort them alphabetically, but in a specific order designated by number e.g. 1,2,3....120 When I created each file, I began numbering them this way. However when I was done, the file system sequenced them in a way I didn't appreciate.. e.g. 100-120 is listed before 20-99, things like that... So I have begun to rename my files, with a leading 3 digit sequence.. 001,002,...120 This is the tedious task that I would like write a batch or macro to accomplish the renaming. I recall being able to create small macros similar to this, in UNIX on the university mainframe.
