Disk Cleanup type thing?
 

is there something like Disk cleanup in mandriva?

If you look in the cron directories you'll see things like tmpwatch and logrotate are set to run automatically. The only other cleanup you would need to do is for stuff in your home directory - firefox or konqueror browser history and stuff like that. Just use the built in 'clear history' and 'clear temporary files' functions in those programs. Linux is not Windows so it doesn't go spewing data and files across the drive like many Windows apps do.
