i just started using portable apps.. some of the apps like firefox and thunderbird have default setting changed(like no email address added to addressbook on mail send or no history for web addresses) to reduce number of writes to usb.
Can I have a portable app that I can use to sync files between computer and usb. So when I start working in office I run the sync app and all the usb data is copied to the computer. I use this portable apps from my computer so I dont need to reduce number of writes. When I am done I sync the folder to update any changed files to the usb. I take my usb home and do the same sequence. This way I reduce the number of writes. The app could have an option to delete files securily from the computer after sync( useful when working from a shared pc).
