    From Mike Halmarack@21:1/5 to All on Sat Apr 30 11:21:37 2022
    Yesterday I restructured an archive folder on one of my shared drives.
    It has so many sub-folders and files it took me most of the day.

    Today I accessed this archive folder from another PC and the structure
    I see is as it was before I started restructuring yesterday. When I
    try to open a file on this phantom structure of the past it won't
    open.

    I go back to the machine the shared drive is on and all is a expected
    and as it should be after yesterday's restructuring.

    Restarting all PCs, shutting down then restarting all PCs has no
    effect. Still the same disparity showing.

    Curious, and interesting - something I've never seen.

    Are you accessing the folder via network sharing notation (e.g. \\myothermachine\sharename) or as a Mounted drive? If the latter, then deleting the mount (net use X: \delete -- where X is the local drive name) and then mounting it again (possibly with a different local letter) could well fix it? Maybe delete the share at the source, then re-share it with a different share name?

    What does a third, definitely-hasn't-cached-the-folder computer see?
    That'll clear up whether it's a client or server side cockup.

    It sees the new structure as it should be. I need to look into
    caching.

    Thanks for the advice and explanation. It's a network share. It turns
    out it was only a problem on one of 3 PCs. I restored a backup and
    it's OK now. From what you described though, I need to develop my
    understanding beyond the GUI options.

    Digging around, I see the "Advanced Sharing" dialogue has "Caching" options. Drill down from the "Properties" dialogue accessed by right-clicking the folder you wish to share. If you turn the caching off (perhaps temporarily) that might fix it. It does sound like a corrupted cache.

    In a multi drive machine would the cache be held on the drive that

    There's clearly a whole raft of stuff related to this that I've been unaware of. Most of the documentation online seems to relate to mapped drives (e.g. M: \mystuff, rather than \\thatOtherBox\mystuff). You can configure a mapped drive to make files available offline, and it appears (from a quick survey) that the location for the cache is C:\Windows\CSC - which is an acronym for "Client Side Cache".

    This article touches on all this: https://www.ubackup.com/windows-10/enable-offline-files-windows-10.html

    the data elsewhere?

    Or is it that the the whole of the data containing machine is turned >>> off and the cache is held locally on the potentially recipient
    workstation?

    This - client side.

    If I read correctly, using a third PC you've proved that there's just
    one client machine with a bad idea of what's on the server? So whatever >> has happened is on that client.

    I'd suggest turning caching on (on that client) and off again, see if
    that flushes it out.

    Thanks Jaime, that mostly cleared it up for practical puposes.
    In a multi drive machine would the cache be held on the drive that
    holds the OS by default?

    I expect so, but only because Windows really doesn't like putting things anywhere else! No idea where.

    There's clearly a whole raft of stuff related to this that I've been unaware of. Most of the documentation online seems to relate to mapped drives (e.g. M:
    \mystuff, rather than \\thatOtherBox\mystuff). You can configure a mapped drive to make files available offline, and it appears (from a quick survey) that the location for the cache is C:\Windows\CSC - which is an acronym for "Client Side Cache".

    This article touches on all this: https://www.ubackup.com/windows-10/enable-offline-files-windows-10.html

    Another article (lost among the discarded tabs now) suggested that doing a drive cleanup (from the Properties dialog, or using cleanmgr.exe, will clean these caches if you drill down into the "clean up system files" level, and include "temporary files". That's certainly plausible - if you have File History enabled, and it's configured to work with an occasionally-connected external drive, FH remembers/stores changed files until the drive is re- connected. Those files can be purged by selecting "User File History" in that list. (Not to be done without a good reason!)

    Thanks for the extra information Phil. I'll study it.
