To make savefile load automatically when you start Angband
Right click the shortcut, there should be a field in properties ‘Object’ where you can add path to savefile, eg:
C:\games\angband\angband.exe “C:\games\angband\lib\user\save\tangar”
Or, if you have the angband directory as working directory, just:
angband.exe lib\user\save\tangar
In linux it would be -utangar
Do I need to take digger into my hands to improve digging or it would work from inventory?
In new versions of Angband when you dig the game uses the best digger from your inventory if you have one.
