Sounds like you didn't have write permissions on the USB drive (bad mount

The bug here would be that KDE didn't tell you about it. Will you please file
it?

although
there was no compression. 6 ea meg jpeg files compressed to 13.5 meg.
wouldn't call that compression. (2.3 (6 X 2.3 = 13.8)

You're trying to compress something that is already compressed. In that case,
the resulting file won't get much extra compression, if any at all. In some
cases the resulting file can even be bigger (no compression plus extra header
data)
