Select "complete"

Ok, Now its installed..That was easy..

Go to C\Program files\DGCA and double click on the dgca.exe file (
The blue icon)

Once the program opens go to File~>Compress folder or Compress file (depends on what you want to do)
Browse the directory for the file or folder.

Click the file or folder once.
Now you will see a blue icon in the top left that says "Archive" Click it.

Look at the options..
You can do alot but for just starting keep the options
as is. Click "ok".

Watch it work. Then click ok.

The file should be in the same area where you compressed it. Now instead of a folder (Mine was a myspace folder) you will have a
file with the .dcg extension attached to it. (Mine is called myspace.dcg)

Now you can upload the file to any website you want and share the files with your friends.
This program has alot of options like password protect and encrypt.. Once you get better use them.
Here is a good start
