What size file for mini chain saw

I purchased a 5/32" file for my saw and it works very well. I have a 10" bar with a small tooth chain. The 5/32" file works great.

Are these 5mm (3/16") or 5.2mm (13/64")? I see both sizes referenced but wanted to know the actual exact size. Thank you

Thank you for contacting Oregon Tool Jim06. This add is for a 12 pack of 13/64" - 5.2mm files. Our 3/16" files equate to 4.8mm. Please contact one of our Technical Services Experts at 1-800-223-5168, option #1, if you have further questions.
