Don't think that's the problem, but agree with what the name immediately suggests. It wouldn't have been very hard to come up with a name that implies "these files are better" instead of "these files are extra large."
XL is pretty well understood to mean extra large, no?
Yeah, that's the only thing I (and I would bet 99.999% of everyone else) have ever understood it to mean.
HF, like a Lancia.
Should've been JPEG SX.
Sounds like a budget car sold in SE Asia / Latin America in the base trim level.
