Hi there,

about a few days ago I was a litte confused about my BOINC-Client telling me, there wasn't enough space left for other workunits (even smaller ones - other projects).
I checked the 5GB partition of my server where only Win2k, BOINC and some minor Utilities were located and it was nearly full.
I found out that my BOINC folder consumed over 1GB of space.

I didn't have any Workunit left in BOINC at that moment besides one SETI and one or two of another project.

Then I looked deeper into it and found out that there were some folders full of .zip-Files inside the CPDN-Folder. 2 of them were 330MB each. - last change was 2004-12-03 and 2005-02-14
And there were two other folders. one of them looked like an old crashed Workunit, because it was dated 2005-02-19 and the other one was dated today.

So my question is: are these files needed for something? - can I delete them safely? - do I have to do something else after deleting them?

They're the results from completed jobs.

CPDN only returns the 7Mb subset of the results that are immediately relevant to the post-processing that the project team do. Participant's systems provide distributed storage for the full set of results.

You can delete them from your system to free up disk space, but it's better if you can back the directory up first in case the project team ask you to upload more data at some future date (a number of users were asked to upload more results from the CPDN classic THC experiment a few months ago).

Well OK then, I'll burn them on CD - so if they are interested, I could send that CD in by mail (that should be faster than uploading 330MB @ max. 16kB/sec)
And it leaves my Harddisk free. Should have installed BOINC on the 20GB Programs-Partition. ;)

Thanks for the reply.

When BOINC tells you that it doesn't have enough disk space to download another WU, that would be a good time to uninstall it, then install it on the 20GB partition.

It's better to copy the complete BOINC directory structure across to where you're going to install it on the larger drive, uninstall BOINC and reinstall it over the top of the copy you made. That way you don't lose work, don't have to attach to the project(s) again and don't end up with a new hostid.
