Sorry guys,
I really want to participate but you show real indifference by not solving the problem of overflow of the disk usage.
There is no option for automatic clean up of the space so that the next projects can be processed automatically.
I am not going to clean manually the space anymore since you don't care.
Well, then I don't care for you too.
If you don't solve this soon I will delete this app forever.
bye

You could start with explaining what your problem is, instead of dropping in in the middle and then ending with saying you don't care.
You could also tell us which BOINC version you're running, on what operating system and with which projects.

BOINC 7.6 has a fix for a bug that was reusing slots without cleaning them up first. 7.6.10 (beta) has a fix for cleaning out the project's directories at a reset.

let's see...
ver.7.2.47 (x86)
I know this issue was raised in the past, and the only advice I've seen from your side was just to delete the project and re-add it again.
However this engages me in many efforts trying to find the login credentials and re-adding the projects all over, just to clear the disk space that is not being released automatically.
Now probably you understand the problem.

We are not paid personnel, nor we have any benefit from this project, and if you really do not want to solve something so simple, it looks I am loosing my motivation.

If there is a new current version that fixes this problem please give me the link to it.
I haven't seen option for automatic update of the SW either.

Make a backup of the account_*.xml files in your BOINC data directory. Since you still haven't said which operating system you run, it's difficult to advise you where this data directory is.

We are not paid personnel

Neither am I, nor anyone developing BOINC these days. So I don't really see its relevance.

If there is a new current version that fixes this problem please give me the link to it.

https://boinc.berkeley.edu/download.php will point to the latest recommended version available at all times. The "All versions" link at its bottom links to possible beta versions as well.

Only Windows and Macintosh are 7.6 versions, the Linux version is still 7.2.47, because of wxWidgets build problems in the past. We're now actively pushing for Linux repository maintainers to build newer BOINC from source. There are also BOINC PPAs (Personal Package Archive) available built by (trusted) users. For example, see https://launchpad.net/~costamagnagianfranco/+archive/ubuntu/locutusofborg-ppa.

I haven't seen option for automatic update of the SW either.

Which will never be added, because it's not secure enough. Besides, the installing party always has to be an administrator, while the running/controlling party can be anything but an admin.

It might also help, to tell us which projects you are using. Some projects keep files much longer than others, even if they're not needed for active tasks anymore.

My Detailed BOINC Stats

I am using Win 7 x64.

And the projects are:
Climateprediction.net
and
World Community Grid

Ok, no body is paid. Then why on first place they did develop the app?
To contribute?
OK, then just create this functionality that will make the app more effective and would not annoy the other contributors.

At the end of the day, someone needs this project, right?

OK, then just create this functionality

Which functionality are you talking about this time?

As I already said in my last post, BOINC 7.6 has a fix for a bug where the slots directories weren't cleaned out when a task that ran in such slot was finished.

A next BOINC 7.6 version will have the additional bug fixed where when doing a project reset, parts of files in the project directory would stay behind.

If you do not want to wait for an official release with that fix in it, you can build BOINC yourself, following the instructions at http://boinc.berkeley.edu/trac/wiki/CompileClient#Windows

If you'd bothered to go to the climateprediction.net web site and look through the forum posts, you'd have seen that models not cleaning up after them selves has been talked about dozens of times. A crashed model will leave behind a number of files, the space of which came accumulate to megs, or even gigs.

Also posted about a lot is that these models are the full blown supercomputer models as developed, owned, and run by the UK Met Office.
They don't like being interrupted by such things as BOINC settings which constantly start and stop BOINC, and hence the tasks it's running.

For reference, my CPDN shows 5.44 GB disk usage... Though I currently have 8 tasks in progress.
