myDSL Extensions (deprecated) :: .deb & .dsl files how to

I just installed DSL on my Hard Drive and need to know hoe to deal with downloaded .deb and .dsl files. All I get when ckick on them is a dialog box asking me what to do, but none seem to define the installation procedure.
thanks

For a *.deb package, I use dpkg -i *.deb

I tried it for *.dsl, but it does not work (it complains it's not a debian package).

We need help here.

Try this for *.dsl:

sudo su
tar -C / -zxvf filename.dsl
exit

You will need to manually edit your Fluxbox menu if you want to add a menu item for your new program.

Good Luck.

Thanks cbagger.
