These files are in c:program files/boinc/BOINC/slots/2 and take up 54 and 11 mb, respectively. The file type is labeled as "Recovered File Fragments". They are growing larger and are frequently badly fragmented. What are these, and is something going wrong that I need to know about? Should I do something to manage these files? I don't see any evidence that anything is failing with my work units. Thanks, Ed |

They are the Cosmology checkpoint files. If you delete them, you'll lose your tasks in progress, them having to restart from zero. These files will get deleted once the Cosmology task is done. |

I take care to keep my system very well tuned, including defragmenting my hard drive every other day. That's what brought my attention to these two files in the first place - in the defragmenter's report. So these are Cosmology files... since they are constantly growing and Cosmology WUs are flowing through my system normally, its apparent that this file isn't deleted once WUs are completed. I'll just drain the Cosmology project queue, detach, and reattach to the project and this should get rid of the files, so they can reappear and start growing again :^( Thanks for the information.

It's possible that the same slot is used for the Cosmo tasks, especially if you have a multiprocessor machine. The checkpoint files cannot be deleted when one task is in progress. Checking your system I see you have two CPUs, so it's possible that while one task is done, uploaded & reported, another is still busy, adding to these files. |

Sekerob - thanks, I always suspend all projects and then completely exit BOINC manager before defragging. I also back up the BOINC directory while I'm out. Ageless - this makes sense. There is always more Cosmology@Home WUs in queue, some of which may have some compute time, preventing these large files from resetting. I've reposted my question to the Cosmology@Home forum to see what they say. Ed |
