Ok, this means that it's not a problem with the format of the modified
files. I have noticed how the files have some glitches when opened in
OpenOffice, specially regarding images. I have heard there have been
big improvements in this are in the last abiword release.

Yes, from 0.84 onwards Sugar will read the whole contents of the usb
stick every time it is inserted, not relying on any database for that.
