Name truncation
Only need this on rare occasions, but do need it to work when I ask it to.
THe one file I have tried to pull out of a winmail.dat attachment had the extension truncated from .PDF to .PD … but that’s not apparent until you drag it out of yhe window and into finder, as only some of the name displays.
Once this is rectified, though, the (attached) file opened as expected.
