When/how do you want to do this?

Assuming you're using bash, you can use the tab key to fill in the rest of the name.  Example:

cd osc<tab>

will fill in the rest of the name, so you would just have to hit "enter."

your can also set a symbolic link

ln -s "very-long-name-of-file-or-directory-you-often-need-to-type" "shortname"

You can also create a symbolic link (shortcut)

ln -s oscommerce2.20.5 osc
but that only works in the parent directory.

Another way would be to create an alias. In bash that would be:
alias osc="cd /full/path/to/oscommerce2.20.5"
that way - typing in "osc" will cd to that directory.
