Hope this could help since you didnt specify what package that you're trying to install.

I think I've finally got the idea that you go - using terminal - to directory where you want to spill the package before you do the extracting.
But I must say I've read things on tar and its cousins, and I have to start all over again, because there was always something I didnt get.
Not sure what my problem is, but I'm back to just leaving the tarboxes lying about, thinking maybe someday..[how embarrassingly bewildered lol] but I'll join the querent in clicking those links from Web31.., and commands from RT;
eventually I'm sure,the sight of a tarfile as a download will not cause a ripple in my operations.
All this, meaning: I can sympathize with querent's plea for crystalclarity!

Make a habit of dropping the tar file into the home directory. Linux is meant to work this way, nothing lies around. Do su - into root. cd into /home/user, then ls shows the content. Do tar -xf <file as you see it there>, the correct directory will be created and all installed as needed. Usually into /usr/local, icons will be somewhere in /usr/share.

Right click on the desktop to Create Link to application. Click Application tab first, do command - Browse. Pick either .bin file or the one with a terminal icon. OK. Click on workpath floppy icon, self-completes, OK. Click on left most tab, click on icon, Other icons, Browse, pick one, OK. Rename Link to Application to suit. OK.

Click desktop icon to start your new app.

Good luck.

wonderful. thanks. (Ireally had no idea wher I might want to 'spill the contents' but didnt want to complicate it any further lol. thats great.
