I have a WinXP computer at one place and a WinVista computer at another. I also go to a day program that only allows use of floppies and CDs. I use floppies otherwise, also. (I have a few older computers.) I'm working on my own technique but want a better method. I have WinMount and it's very useful. However, the technicians at the program don't want anything installed on the computers there, so I need a better, portable method. I'm asking this because I am working on software that sometimes require >2MB storage for source and temporary files and I also bring in some larger programs--mostly games--for the other clients to use. Is there a way I can compress the software and use it at program? Or do I have to create my own?
