Electronics Softwares

I'm a student of electronic engineer and one of the thing that pissed me off the most is the garbage left by this programs with its automatics backups of the projects... each backup can occupy 10 mb or even more... just imagine that you have 10 projects in each software... al least 300 mb in garbage...

for knowledge I'm running this versions: Matlab R2007a, Metrowerks CodeWarrior CW08_V5.1, Metrowerks CodeWarrior CWHC12_V4.5 and LabVIEW 8.2...

Would be very very nice if is added the feature to clean the garbage and history of those softwares... It will be very popular for university uses... all the engineer careers uses Matlab and LabView... ;)
