Looking at some tasks in CPDN testing branch I was somewhat surprised to see the tasks reported as having a peak usage of only 12.91MB. This despite the fact that the amount of disk taken up by the -dev branch running three tasks was almost 18GB. Having asked about this another mod/tester for CPDN said that BOINC only reports on the space taken up by the task in the slots directory. Is it only CPDN that has this discrepancy with most tasks outputting data to a task directory where it is not picked up or is this commonplace?

Things look suspicious. I checked two projects "properties" and what they report agreed for Einstein but not for WCG.
WCG claimed 978mb but file sizes add up to only 230mb

Did you check for hidden files?

I have my file manager showing hidden files by default but that isn't really the issue. I was referring to the difference in the reported maximum disk usage on task pages after the task is finished and how much more disk space BOINC is actually using. I was told by George that he thinks the disk space reported on the task pages of the finished task only reports the size of the slots directory but all task types for CPDN apart from the OpenIFS tasks that still haven't progressed beyond testing output most of their files to a directory with the task name, leading to in the case of these testing tasks several GB actually taken up by the tasks which only reported a few MB.
