Export/import extended memory files?

What mechanisms are there for exporting or importing data and ASCII files in extended memory? Does it involve exporting and manipulating a .d41 state file, or is there a more direct approach?

At the moment, there is no 41X-unique mechanism, only the same options as available for a 41 w/o HP-IL, which means fairly limited. You can (with work) find and extract that from the state file, though it also can be done by copying ExMem files to HEPAX RAM, saving and copying the .ram file and extracting from there. Both processes involve digging out the file from a larger, binary container, so not trivial; it's likely easier from the .ram file as there is less to wade through and the HEPAX file system is better documented in several posts on the MoHPC site in recent months in threads with Sylvain, Angel and others. Here's one of them - https://www.hpmuseum.org/forum/thread-1 ... #pid127638

Alright, thanks for the info. Hopefully we eventually end up with something that's as simple as importing/exporting raw program files in main memory.
