run.sh filenames

run seems VERY fussy about the name it gets,, you should add a warning
It seems it MUST be XXXXXXX_00,  for example K121 expands to K12110f_00,,
behind your back, script fails.. Orig name,, K12110f_00_0912 also fails
When you give the name it wants, it seems to work ok, a bit slow
Too bad there is no way yet to repack
