I can confirm Seekers info about open files, only a few (in normal operation, indexing not in progress). Some open index.dat + SHDOCVW.DLL (IE), one hostslist.txt and one file for each running job, partial or upload. Nothing else.
I'm currently observing memory consumption on different clients... didn't get a clue where all the memory goes to.

Don't share your whole harddrive? (Can't reproduce Xolox opening every file on my system)

Some newbies share their whole harddisks, isn't it obvious?
