SCCM 2012 and .PCK files - how exactly are they used? RRS feed

  • Question

  • Ok, no one, not even Microsoft engineers can seem to provide a clear and definitive answer on this topic, everyone's understanding of the .PCK file with relation to SCCM 2012 is clear as mud.

    I understand what .PCK files are...in the SCCM 2007 world, and how they work, all that jazz, what I don't understand is how/when/why they would be used by SCCM 2012...it seems that sccm 2012 would only need these .pck files during a reassignment of a shared DP in a migration scenario...even that surmise is sketchy since I've watched very closely the DP content conversion process and at no time did the server access the .PCK files to populate the single instance store.

    I am going to do some more testing on my own, my ultimate goal is to permanent delete the contents (not the folder itself) of the SMSPKG folder, essentially all the .PCK and .DL$ files to save space on my server.

    If any soul out there knows..not guesses...the purpose of the .PCK file in 2012, let me know please, don't just copy/paste other people's posts as an answer, explain in clear terms each step of the process that 2012 would utilize a .PCK, or if the answer really is that 2012 does not use .PCK files at all, let me know.

    I have a single primary site with 16 secondary sites in my SCCM 2007 environment, I'm migrating to a single primary with 16 distribution points...so even if .PCK's are used to populate secondary sites, I should not need them since I won't have any secondary sites once all of my DP's are migrated...yeah?

    Thanks!

  • So a MS engineer told me it is safe to delete the .PCK files after the DP has been reassigned and all content has been converted to the SIS, he couldn't explain when or even if the .PCK files were referenced during the DP conversion, but I guess I'll take this as an acceptable answer. I've deleted the .PCK files from one of my reassigned sites and have had no issues so far.

  • pck files are only used when it comes to content distribution to child sites as far as I know. They get deleted after the content made it to the child sites. I am not sure about their role in a migration scenario.

  • Thanks for the reply Torsten, that would make sense if my primary site had any .pck files at all (my sccm 2012 site that is) only my DP's have .pck files. I have no child sites in my 2012 hierarchy unless DP's are child sites (I thought secondary sites are child..) When my DP's require a package they get them from my primary site, not other DP's. I have no 'Pull' DP's setup.

    If SCCM 2012 uses a 'single instance store', which contains 3 folders itself that seem to contain compressed versions of the package files, then there should be no need for another folder that also contains compressed files...just a thought.
