Comment 5 for bug 197647

You are not so bad. Today I discovered the tracker folder on my brother's account to be 5.5 GB! He only used my laptop for 5 days, watching movies, internet, chat, and he started complaining about Linux becoming sluggish.

I don't know what those caches are, but to get 5.5 GB in 5 days (from creation of the user account until I discovered it) it's a bit ridiculous.

This is a bit "aggressive" from the OS side to "expand" like this and "take over all the available space"
