Version control without internet?

[iblis432]

What I did last year was at the beginning of each day or after a major change i used 7zip to compress the entire project and name it xx_xx_xx_vers_y

where xx_xx_xx was the date and n was the version of it that day. so the first one of that day would be 1, the second 2, so on and so forth. I found that useful because 7zip compresses and decompresses easily, has shell integration, and there's no real setup to it. You just take a break for 1 minute and zip it all, then if you need it back, instead of going through any menus or anything you just right click the file and go to 7zip>decompress to /xx_xx_xx_vers_n

Anyway, that's what I did, never bothered with any version software.
