Hi There, As you can see first time, So please do not laugh.
OK! to the problem, I have an old 9.10 ubuntu linux and no more advancements can be put into my system, my PC shop personnel at Battle Ground Computers told me I have no more room, SO, I went looking for a disk clean having never done it for the last year and half, but when trying to find a cleaner that was a Linux type product, all I could locate was some off brand outfit stating WE CAN MAKE YOUR COMPUTER SO FAST YOU WILL WIN THE INDY 500, I got hooked once before by an outfit like that and it cost me an arm and a leg to get things fixed.
So there in lays the crooks of the matter, IS there out there on the web a product that I can trust, that I can use, that will get me some more room, just by doing a clean up, I am now so slow I have to count to 5 when switching screens or I jam up or I have to go all the way out and sign in again.
Thank you for your help in this matter

As far as I know there is no commercial -- or single "product". Linux doesn't work in the same way as Windows, to put it very simply.

Some programs create thumbnails (of pictures viewed) which can take up a great deal of space. will reveal them. For example (from my box)
/home/john/.thumbnails/normal/feb5b3230530613284cf38cd253df3cd.png

You can safely delete them.

Mozilla (or Iceweasel) will create a cache. This can be deleted.

Study the documentation on apt-get remove You can also look at removing log files. (Google or search here.)

If any partition gets past 80% full it will have a detrimental effect on performance.

You might like to look at getting another -- or a bigger -- hard drive, but the fact is that everyone's install eventually grows to take up all available disk space. Or consider using a portable hard drive as a back up for your data.
