Update:
I used Iexpress to create a CAB file but when I convert it to CTX it says there is no data.
My conundrum is that there are a number of observations that were collected on a tablet and did not show up when we downloaded to the desktop (also not in backup, staging, orphans). BUT, when I opened the DAT file from the tablet backup I could see the notes from the missing observations (highlighted) so they were saved and are in there in some capacity but did not download. Is there a way to recover that data so it is usable??
Thanks!
