"csdl_source_542.zip" I just cannot figure out which CSS skin this was, and I would rather not search through all of the skins I have so I can figure out which one it is. So, if anyone knows, which skin is it?

Thanks.

Well no one will be able to find out because most of the files names are randomly generated. It would be better if you can remember what you were downloading, otherwise no one will know.

just make a copy of your current cstrike folder, delete it, install that skin and, when youre done, replace your cstrike folder again.
