Open Winrar and start the "Wizard"
select "Create a New Archive" and click "Next"
A window will open to select the file or files to add to archive.
Browse to the folder with the files to add, highlite the files to
add to archive. Once selected click "OK"
The next window will be the "Archive Name" window. Give your
archive a name and click "Next"
under "Archiving Options" check the "Faster, but less tight
compression" box. Click the drop-down window under "If you
wish to split the archive" and input the individual file size in
bytes...For your needs 50,000,000 would give you roughly 5
files. For standard and more reliable file integrity (only from my
experience) I would choose 15,000,000, but this would give you
more files to unrar---its your choice.
You can also check the "Create Self Extracting Archive" box if you
When done click "Finish" and the "Creating Archive" process will
Make sure you know the location of the folder where the archive
will be placed. I think by default it will begin to place the archives
on your desktop unless you setup a folder location ahead of time.
