When I use Linux, I love that anything I place in /tmp will be wiped when I shut the system down. Windows, out of the box, doesn’t do this for your %TEMP% folder. Google this, and you’ll find many people advising to install one free tool or another. I am very wary of unnecessary installations on my Windows machines. The advice given here at WindowsForum.org requires no installations. It was meant for Windows XP Pro, but I found today that it worked just as well on my Windows 7 Professional system.
Unlike the fixed /tmp location in Linux, Windows determines the value of %TEMP% and create that folder dynamically at every login. Firefox doesn’t seem to accept %TEMP% as a valid value in browser.download.dir on about:config. Therefore, I
- keep a sidebar shortcut to %TEMP% in Windows Explorer, and
- select “Always ask me where to save files” in the Downloads section of the General tab of the Options dialog.
That way, it is easy for me to select my %TEMP% folder when downloading in Firefox, as well to access it from Windows Explorer.
