Disk Space

How much disk space does CIS (free) take when it updates. I am running Win 8.1 on a Asus tablet with 32 gb c: drive. The program seems to be about ~100 mb when installed but I am losing 1-2 gb periodically with Windows updates and CIS updates. Is it possible to install the program and updates to an sd card?

Only if you change the windows temp directory in environment settings.
