SP V7 creates a folder C:\tmp on the user's system. In that folder, SP places a log file named MM.log.
During beta testing this was brought up and a request was made to not create an ambiguous tmp folder but to clearly identify the folder via a StickyPassword name and place it somewhere else other than the root C:\.
The response to this request was "In the final release it will be on one place and only when needed."
I again make the request that SP use a uniquely named location to place MM.log and that it not be at the root location of system drive. It should be placed under %SystemDrive%\Program Data or %SystemDrive%\UserAccount\AppData\Roaming or even in SP program folder at %SystemDrive%\Program Files (x86).
