Disk-space eaten

[Tal Achituv]

Hi!   What would be a good way to discover what is eating disk-space?!   Currently - I am checking diskspce periodically (every 10 minutes) and about 5 megs are gone each time...   I suspect that some backup routine is running in the background...   1) what else might it be 2) what is a good way of checking:     - What files are currently in use     - What is the size of a folder and all its subfolders       ( for tracking changes and by that detecting the "busy" folder)   I guess I am missing some basic utility knowledge here...   Thanks, Tal.
