Windows 10: slow access to hd with millions of files

    slow access to hd with millions of files

    We have our security cameras recording to a 3 TB hard drive and it tends to get loaded with LOTS of files, well into the millions, loaded into subfolders based on camera, year, month, whether photos or videos (ex: f:\hikvision2\2017\01\photos). Access to this hard drive has become cumbersome - it takes minutes just to get a directory listing.

    I've already gone down the "change to general file type instead of photos" route, still slow access.

    I'd be interested in getting input on how to best address this issue and be able to maintain a history of files from the security cameras.

    Possibly switching to a NAS RAID server or USB 3.0 RAID server with at least dual hard drives? If you went all out for a 4 drive servers, there are different raid modes that would offer both drive failure recovery capability and spanning across more than one drive to increase performance.

    Windows Explorer has always had problems with large numbers of files/folder. You can run Process Monitor - Windows Sysinternals | Microsoft Docs to see what files Explorer is accessing just to confirm it's not doing anything weird. But from personal experience once you get into the 10s of thousands of files there's not much you can do.

    You can try a different file explorer app or do things from the command line. There may be existing solutions out there for security systems like this. But a custom front-end wouldn't be hard to write if the folders are well-organized.

    Edit: This is assuming you have thousands of files/folders within a single folder level (e.g. \folder\00001, \folder\00002, ... , \folder\99999).

    The hard drive is actually in a Synology NAS, so, don't know if that's got anything to do with the access performance. But, there are thousands of jpg files in each directory - when a camera triggers the system sends jpg snapshots to the hard drive, at least 5 pics each time it triggers. At night when we have spider webs waving across the camera, we get triggers about each 10 sec, all night long. Same when fog rolls across all the cameras: boom a lot of cameras trigger and send snapshots do the hard drive.

    So, the hard drive is chock full of jpg files and even getting to the drive to delete files is a pita since you have to navigate down the directory tree and each move takes several minutes.

    Use Date Modified instead of Date in the Column Headers

    Not sure if this helps you but I've seen my response times improve when I did this:

    You said that you have tried "general file type instead of photos" without success.
    I, too, was unsuccessful when choosing "photos".

    Instead I find that the best choice is "documents".
    Try that. It worked for me with both Windows 10 and Windows 7.

    No change, I've tried that route several times with no change.
