Yes it is possible. From Gallery --> Options --> Move/copy
to folder and you can select memory card as your destination
folder.
If you intend to do more complicated stuff like moving multiple
files and tired of Gallery's loading time, you can download a more
flexible application called
FExplorer
Just for your info...
.jar files are usually Series 40 games (6610, 3200, 6230 etc). .sis
files can only be opened by Symbian phones (6670, 3230 7610 etc).
Difference is the .jar will be smaller screen size and i suppose
simpler games. Installing .jar files on Symbian phones will show on
top left of the screen filling about half the screen size only.
