I have more than 900 files named in the format Raw Data ###.png and when I pass file Raw Data 999.png, the next one will of course be Raw Data 1000, then 1001 etc. This is going to cause some alphabetizing problems, not in the Windows directory tree, but in my Excel spreadsheet where part of the filename must be stored as part of a text cell and is used as a sort key.

Is there a quick and easy way to add a zero ahead of the "###" part of my 900+ filenames in Windows, changing the name from, for example, "Raw Data 092" to "Raw Data 0092" for all the files? I can deal with the changes in Excel with a couple of search-and-replace runs, but I don't have that option with the Windows directory tree.

For perspective, I can create a macro in my programmable keyboard that will allow me to change each individual file with a single keystroke, so if the solution is more complex than repetitively pressing a designated key 925 times I'll probably just do that.
