[Qgis-user] problem with RECLASSIFY (GRASS)

[Azzurra Lentini]

Hi Chris thank you for the explanations.
Anyway I gave the output folder path so why it should save the output in
another location. Furthermore I searched in my PC but i don't find this
output. Anyway this command is well working in this new version Qgis 3.16
so for the moment I am ok.

Thanks again, Azzurra
