Hello,

If i understand well form you post above, you have only one folder named "and" in your root folder which take a lot of space.

I would suggest to delete or move it.

From the name i think this is related to nitroid so not necessary for maemo and as said before, nothing should be stored in the root folder.

EDIT: I checked on my n900 and do not have this folder. I then assume you can delete it without worry. But i never used nitdroid before and do not know what the deletion will do on youd nitdroid install.
