I was making a loop of oregon 33 .325 050 today and need to make a few more by Monday.  This chain used 5/32 files right. Pretty sure yes. 3/16" file just didnt set right IMO to use.

When I run out of the oregon LG33  roll I was going to 20LPX  (does the lpx use bigger 3/16 file?).    Maybe try carlton K1L .325 (file size ?) and I know I like the stihl 23RS  3/16 file size.

The correct file size for the 33/34/35 Oregon chains are 11/64" (nominally 4.5mm, but really 4.4mm). Stihl Topic (23/25/26 TS or TM) chains in .325 take the same size. The chains have low profile cutters, but a regular size chassis.

There used to be similar chain in 3/8" as well (Oregon 76 and 77 LG, Stihl 33/35/36 TS and TM), that take a 3/16" file.

20/21/22 LP/LPX take a 3/16" file.

Never mind thought so.  FILE SIZE: On these chains you may use either a 4.5mm or a 5/32” round file and file guide.

Yep old news as I have owned them all since that post you quoted.

OK, I didn't notice the post date. My point really was that 4.5mm files are 11/64", and not 5/32".

Yep agreed on that.

Per oregon you can use both.
