Windows Batch File To Back Up Source Code

Hi! I've been using a batch file to back up my source code. It's very easy to use: just right-click the folder, point to SendTo, click "Backup w 7Zip" and type in the subfolder to which to back up the folder and press Enter, and your source code will be backed up. It backs up source code, so it will remove files from the backup that should be rebuildable, such as .exe and .obj files. It requires a little setting up, though. If anybody here is interested in this batch file, just ask for it, and I'll clean it and a batch file that grabs the current date and post it here.

BTW, I remember a long time ago browsing a site with a lot of batch files to download but don't remember where, and I couldn't find it on Google. Can somebody here link to me such a site, please?
