I found this procedure very easy to do so i thought someone else might find this info helpfull. I have FX 5200 and LXDE Salix and here is how it works at least for fresh LXDE version:
1. Get&Install(i did full option) Salix if not done already;
2. In terminal do slapt-get --update after it is done ...

DeepBurner is great freeware and ImgBurn is ok aswell.

I think you have to empty the wastebasket too, though I'm not sure because I don't have an LXDE installation. Or did you do this, and still not gain any free space?{...} There is no visible trash for this LXDE version..
This is just a guess, but... deleting a file in one partition won't free up ...

Hello. I downloaded LXDE Live 13.1.2 CD of Salix and installed to HDD and i enjoy it but i have one annoying issue - whenever i delete any files with default PCmanFM(0.5.2) the amount of free space isn't increased but stays same. Is this bug or there is hidden trash somewhere? How could i fix this ...
