Running Thumbnail generator in a system with Primary and distributed file managers

Hi All,

Trying to fathom the workings of the Thumbnail Generator in a multi file manager system. 2 Questions:

1) Does it mater where you run it from i.e. PFM or DFM

2) When you run it with the check status switch, what do the results mean, in particular we have a lot of errored thumbails is there a way to find out which errored so we can diagnose and run again rather that runn -ALL

OK three questions disguised as 2

Thanks

Adrian
