My computer runs Windows 10 and I work with Java and Eclipse. Recently Windows warned me that I'm running into short disk space and after some study I noticed that I have a folder named `.m2` under my user's folder (`C:\Users\MySelf`) that occupies 202Gb.

I know this folder belongs to Maven. Since this folder is bigger than all my projects and their dependencies together, it seems to me that Maven is keeping unnecessary files, so I want to get rid of them.

Is is safe simply delete the folder contents or should I run some particular process in order to save space and keep Maven working well?
