In QGIS Desktop 2.18.14 with GRASS 7.2.2, I started cleaning vector layers and it worked nicely.
Issue: every time I load a shapefile onto GRASS Plugin by
v.in.ogr.qgis), it creates a map (its own vector set) within GRASS Database.
How can I remove these maps? Most of them are just temporally files and I do not want them to stay in the harddisk forever.
In earlier documentation there appears a module(?) "GRASS Browser" which could be used to delete maps, or probably
g.remove in GRASS (standalone) is the function I need, but I cannot locate them.
EDIT I might have begun with a wrong assumption that we needed to clean mapsets / maps levels. GRASS users can simply remove Location by deleting the folder and start over. It seems fairly practical way to deal with pile of maps.
