move .p2 folder to a different drive [message #1775083]

My main drive (C) gets low on storage. The Eclipse .p2 folder takes up a lot of space.

I've installed several Eclipse instances by extracting an official zip on a different drive (D). These instances seem to still use the .p2 folder in my home on C.

How can I move the .p2 folder to D and/or how can I create a new .p2 folder on D and make my Eclipse instances use the new one?

Eclipse IDE for Java Developers
Version: Oxygen.1a Release (4.7.1a)

OS: Windows 10, v.10.0, x86_64 / win32

The installer uses a shared bundle pool kept in ~/.p2/pool by default; you can change it via the menu. But you said you unzipped packages. The rest of what's on ~/.p2 is generally just a few caches that I don't imagine should take so much space. What is taking up so much space in your ~/.p2 folder?

Well, it does not take much space, my measurement was wrong.

So, if it is only cache and installer stuff, it should be fine to delete it, right? And what about moving it?

As long as you don't have a pool in there then it's basically only p2 caches, so deleting is okay, but it will force p2 to refetch the cached things the next time, making it slower, and they'll come back again as well.
