I have an old Jonsered 625 with an 18 inch bar, marked on the bar is 3/8 - 05.8 on the chain itself the cutting teeth have a 25 stamped on them and on the chain links is husqv. Went to Lowes asking for advise the guy sold me a 3/8" filekit which has 7/32"(5,5mm). He said it would work BUT is it correct ? Some advise before I use it.

yes 7/32" file is for 3/8" chain
.058 is your chain gauge and does not change the cutter size
 
It means 25 degrees is the proper sharpening angle. That would be a good angle for hardwoods. And if your chain has a witness mark on the back of the top plate it will give you something visual to sharpen to. Either 25 or 30 degrees will work well. The sharper the angle the shorter time the tooth will remain sharp. But inversely, the faster the cut.
