Trashcan behavior seems odd

[Ignazio Palmisano]

Hi all,
I'm a Linux newbie (and Kubuntu newbie too). I installed 5.10 a couple 
of weeks ago and started installing lots of things I needed, such as 
Eclipse and other nice little programs of about 100 MB each. Not 
surprisingly, the space on my root partition ran quite low (I installed 
Kubuntu in a 5 GB partition), so I moved programs up and down my partitions.
The problem is, I found a folder:

/home/ignazio/.local/share/Trash/files

that seems to be the folder in which the trashed files go until you 
erase them for good. To my surprise, there were about 1.5 GB files in 
there, resisting my efforts to empty the basket, and all of them were 
files I deleted hours ago.
Is this expected behavior, or maybe did I manage to put some switch wrong?

Thank you very much for your answers, and please excuse the naivete :-)
Ignazio
