Reducing memory usage by shortening file names

Blitz3D Forums/Blitz3D Beginners Area/Reducing memory usage by shortening file names

I was wondering, how much difference does it make if you load image files with shorter names? I think I'm getting to the point now where my engine's starting to slow down or at least take a lot longer to load possibly because I have mostly all long names for my pngs. The reason I have them so long is because it helps me to have them be as descriptive as possible while I'm still designing everything, but if shortening them to 8 letters or even 4 later would speed things up, I'll do that for the final exe.

My biggest questions are,
1. If there is an effect, does it speed up just the initial loading time, the speed of the program while it's running, or both?
2. Would not using a file path and just putting all the files in the same folder help?
3. If 8 letters is faster, is 4 even better than that?
4. Do the characters used in the extension count, like does .png add an additional 4 characters?

Thanks, I'd test this all myself but I have over a hundred files now for my dropdown menus, and changing them all to 8 and then 4, plus changing them in the code would take forever, so I thought if someone here already knows that would definitely save me some time.
