chain with right file

[bohawg1]

I have a chain i picked up from were i got my stihl and whats wrote on it is 325.74.0 do you know what size file i need for this chain. My father inlaw picked me up 3 chains which i think he picked me up the wrong files. Hadnt had time to call them to find out and i thought i would ask on here se if i could get a answer tonight,, box says oilomatic3 stihl. Thanks if you can help

Assuming its 325 chain, then I believe 3/16 would be the appropriate file size.
