I heard someone say you should do the 1st few filings w/ a file that's just under 3/8" for a 3/8 chain. Anyone heard of this before?
I've used 7/32 on used 325 pitch, which makes me think that a 1/4" or 5/16" file on a used 3/8 chain would be better than a 7/32 or 13/64.
Has anyone tried this?

Most will use a 7/32 file and then some will use a 13/64 when the chain gets nearly worn out.
I think the main reason why a file is the size it is, would be because if it was much bigger it wouldn't fit between the cutter and the racker on a new chain.

So have I, but only on "rocked (or spiked) out" chain, to remove the damage faster.
I wonder if a 1/4" file would make a thinner under the top plate angle? It would seem the bigger the file the longer it would last as well. The bigger file would be good for gullet work and rocked chain as you mentioned. I still need to get some goofy files and try those since I am one lousy square filer. Lol
