It where you can save the svg on to your files. I'm surprised you haven't done this yet, it resolves you having to save the normal file over and over again.
If you just click download svg file and save it onto your files. Next time you update the map, click on svg instead and use that file to save and add.
Exactly it does that's the svg file. Save that on to your downloads or desktop somewhere. Then open the svg file next time you want to add to your map, then you don't have saving problems. ;)
Edit: The orginal file isn't the svg file. Having a svg file also solves the promblem if you lose the orginal file.
1. I wanna download Inkscape to continue working on map, how can i find out which version I used before? 2. Can I download newer version of Inkscape and continue working?
Help: I want to download inkscape but when I go to inkscape.org I can only download newest version. I don't want to do this because my computer is very slow. Where can I download older version of Inkscape (link, please)?

What?
A newer version doesn't mean it is a larger file, or that it is harder to handle. Even if it is, it will not differ significantly. Just download whatever version they're offering.
