    It’s 9:14 pm EST and free space is now 86.9 GB. Was 96 GB 41 minutes ago.
    Could there be a connection between virtual memory and RAM?

      Windows.edb is the cache file for search indexing. I recommend you deactivate it and delete the file. Here’s how to do so

      [ul]
      [li]Search for “Indexing Options” Open it.[/li][li]Search “services” (or run “services.msc”, or use task manager’s services tab) and find “Windows Search”. Stop the service.[/li][li]Delete the Windows.edb file from C:\Program Data\Microsoft\Search\Data\Applications\Windows[/li][/ul]
      For SSDs, you may not want to index your drive - a search will be quick without it and it’s a waste of space as well as unnecessary wear and tear on your SSD. In the indexing options box, click Modify and uncheck any SSDs you may have. You may want to keep the start menu indexed - it should show up as an included location. If you have any libraries located on your SSD, remove them from the included locations. If you have another drive on your computer that is larger than your SSD, you may want to store the index file there. Click Advanced and under “index location” click “select new.”
      Click Advanced in the already-open “Indexing Options” panel after the service restarts itself,then click rebuild.

        I do not see a Search folder under Microsoft and cannot find the .edb file. ( I know that Show Hidden Folders is checked under Advanced Settings. )
        Also, the SSD C drive was already unchecked under Indexed Locations… see below…
        If I stop the Windows Search service, I am unable to Modify Indexing Options as the Modify button will not be highlighted.
        Must first Modify, Rebuild, then stop Windows Search under Services.msc as last step.
        I’ve changed the .edb index location to the D drive, clicked Rebuild, & stopped Windows Search service.
        Should anything else be unchecked below?

          I’ve rebooted my pc after making the changes above but C drive free space is still dropping, but at a slower rate. Every few minutes an Indexing scan will start as shown in the Indexing Options screen, which I think relates to the 2 TB D drive.

          I’ve disabled indexing for the 2 TB D drive, rebooted the pc, and C drive free space is now 171 GB
          The Indexing Option screen was initially paused and has now started to index items, which coincides with the hard drive indicator light to flash.

          Is it normal for indexing to kick in every few minutes?

            If you don’t want indexing to function at all and you don’t mind search not working as it should, you can set Windows Search to Disabled That’ll prevent it from indexing at all.

              I thought of that, to disable Windows Search, but this was never a problem before. So I’m curious as to what is triggering this new behaviour?

                Sometimes Windows gets a bunch of files and then it just indexes them. It indexes every file stored on a HD, including temp files, cache files, etc. Sometimes it gets too much and it just needs to be disabled.

                After disabling Windows Search, your free space should remain stable. Check it and verify

                    OK. Windows Search is disabled but free space still dropping, but much slower. Was 164 GB, 40 minutes later, now 159 GB.

                      Thanks for taking a look Rustys.
                      The only thing that stands out are the NVIDIA files which appear to be about 16 GB. The NVIDIA backend.log.bak file is 9.3 GB alone. (The NVIDIA areas, backend & Corporation flash with activity in Space Sniffer, quite often.) People have commented/complained in various forums about the latest drivers which now have “telemetry” aka tracking malware embedded.

                      Once suggestion is to Disable the NVBackEnd ?? or delete the Vulkan RT files ?
                      I have a new pending NVIDIA update to do. I’ll do a Custom update, selecting only the GPU Driver and PHYSX, and also check the CLEAN INSTALL BOX.
                      Let me know what you think.

                        Delete backend.log.bak and see if it gets recreated and takes up space. If so, the culprit may very well be nVidia. backend.log.bak can be found at

                          See if this resource helps with this.
                          Remove Nvidia telemetry with Autoruns. 13.62

                            I’ve deleted backend.log.bak. Soon as I did that my C drive free space jumped from 157 GB to 169 GB.
                            Also, the backend.log file which is a text log keeps changing, over 3 GB & growing. Will be deleting that too.

                            But I’d like to disable NVBackEnd … and I see Rustys just posted a solution.

                              ** After 17 minutes, the backend.log file is now 6.8 GB. NVIDIA, THIS IS RIDICULOUS !!!

                              17 MINUTES LATER … BACKEND.LOG FILE NOW 6.8 GB, UP FROM 3.05 GB !!! ( backend.log.bak file already deleted in screenshot below )

                                so nvidia is to blame. Go ahead and follow gus’s guide that Rusty’s posted and that should hopefully eliminate nvidia’s encroachment on your free space
