I think stihl uses a smaller file because the tooth isn't as big on their 3/8 chain.  If you look at a new stihl chain and a baileys chain side by side the stihl looks smaller in the tooth.  The difference isn't much but you can tell how different the file sits when you try to use the wrong one.

Although that is the opposite of the .325 chains.  Stihl has the bigger cutter on those.

When first filing a new Stihl chain, the 7/32 as well as the 13/64 files didn't fit the factory shape of the ground tooth. But the 7/32 file would reshape to the file size with one stroke for me.

Yes, the Stihl 3/8" cutters are lower up front than on most other 3/8" chain.

OHH OK. I thought it meant to file with the 7/32 first, then take the smaller 3/16 after the 7/32. But I understand what your saying now because of the rack of the tooth it will need a smaller file as the tooth wears down. Yes. I understand the depth gauge, I've just never thought to use a smaller file as the chain wears. So if this is the same 3/8 .050 chain as my Stihls, why does this one call for a 7/32 when Stihl calls for a 13/64? Thanks for clearing that up for me.

I use 13/64 files on all my 3/8 chain, even non Stihl chain, I find it bites a little better, but still cuts smooth.

I find the difference between 13/64" and 7/32" isn't really a big deal, as long as the file is held at the correct height.

The smaller file will of course create a little more "hook" than the larger one - for good and bad....

To be honest I can't see any difference in the side plate profile size of both the Oregon LP/LG .375 and Stihl RS .375
I think Stihl went to the smaller diameter 13/64 file to make hand filing easier with their "heavy duty" harder to file cutters :D
