Java files can be a bit tricky at
times. Most of the time, after you
have downloaded and saved the
java file on your pc, windows
tend to change the icon &
extension of the file into a .zip.
And this will led to those not
familiar with this issue to extract
the file. Once that is done, you
will see a lot of folders and files.
This is not the right way but
ofcourse theres a way to get
around this. Heres what you
should do instead;
First, on your PCs, launch
Windows Explorer and then select
Tools>Folder Options>View and
"un-tick" the Hide extensions for
known file type.
Now only can you see the full
extension of a file and change
the .zip into .jar and send it to
your phone.
