   I suspect the only real negative effects *might* be with eMMC storage, though it's the sort of thing that drives me nuts. What's happening is that Windows creates a Bunch of tmp folders -- almost 1300 in the copy of Win10 I'm using right now. The name of the folders starts with the letters "TW", & they all have the .tmp extension. They're located in C:\Windows\ System32\ config\ systemprofile\ AppData\ Local\ [you might have to set the options in File Explorer to show hidden system files, have to be logged in as admin., & will have to click through a message that you don't have permission to explore the folder].

   OUCH!

   With apologies because this is a bit awkward, while sorry you had to go through the hassle of deleting All Those files, I was secretly Very glad to see your post, because it meant I'm not the only one bothered by this.

   No offence taken, I've just deleted 1750 of them tonight. Selected all then deleted in about 8 seconds.

   FWIW, you can also use PowerShell [in Win10 right-click Start Button] with:

   Remove-Item C:\Windows\System32\config\systemprofile\AppData\Local\tw*.tmp

   If you wanted to get fancy you could set up a task to run at whatever interval, e.g. once a day, once a week etc...

   Does it hurt your computer having all those files on it? Does it take up memory or storage space?

   Practically speaking, it shouldn't hurt anything at all -- I hate it because "It's Not Correct" -- "Windows Should NOT Do That!!!". But if it doesn't bother you that way you shouldn't notice a difference if you leave these folders alone or delete them.

   That said, there's probably an infinitesimal impact since it's something else for Windows and your security software to keep track of, plus Every file or folder takes up some storage space somewhere. Windows considers folders a special type of file, and the file system itself stores their names and locations. On a conventional hard drive, file system tables take up a tiny, Tiny fraction of the whole storage space, but a conventional hard drive is also pretty efficient, writing data more or less directly to the platter(s) where that data is stored. Because of its dominant focus on backwards compatibility, the PC industry didn't invent new interfaces for flash RAM drives, so these storage devices pretend to be conventional hard drives, and those same file tables **may** have more impact, depending on how the drive was engineered. If you have 20MB of tiny files on a USB stick they'll take up more space than one 20MB file, so I *suspect* that in some cases, like eMMC drives, you *might* see something similar -- I'll know more next week when I update my tablets with their 32GB of eMMC storage.

   I haven't seen any more of these files in the last few days but what I do have is a load of CM*.tmp files in the same place, varying in size and dates, all of them with 2021 dates. I have googled to see if I can understand what they are for and if they can be deleted, but am none the wiser. The CM is followed by a series of numbers and letters and the first link took me to a company selling tractors :-?

   This Link is about IBM CM servers, don't know if that is relevant or not. Anyone else see these?

   I've got 20 of the tw folders from the 6th, & 20 for today, the 7th. I've got a dozen of the CM* files going back to 6/2020. Most of those CM files are 1KB, so I opened one in Notepad -- on the 3rd line, after 8 characters that aren't included in the font used, it says:

   V e n d o r M S F T D i a g n o s t i c L o g E t w L o g C o l l e c t o r s D e v i c e P r o v i s i o n i n g T r a c e C o n t r o l

   Googling "Vendor MSFT Diagnostic Log" [w/out quotes] I got this:

   docs.microsoft[.]com/en-us/windows/client-management/mdm/diagnosticlog-csp

   CM **could** represent Configuration Mgr., though far as I can tell that's not really used for or with our home setups. So my next **guess** is that the CM file is a temporary file used in creating a log file or entry. So I searched the Windows folder for "modified:11/2/2021 3:43 PM" [w/out quotes], which is the time of the latest CM file I have. I didn't get any log files, but several .aux & .dll files in Windows\ Assembly\ NativeImages_v4.0.30319_64\. The .aux files are similar to log files -- Googling on ".NET .aux files" [w/out quotes] gets this:

   stackoverflow[.]com/questions/17681514/what-is-the-format-of-ni-dll-aux-files

   SO... I had installed several apps that day [11/2/2021], clearly something was added regarding .NET, because new files. Ultimately my *guess* is that the CM tmp files are leftovers from a Windows process collecting data, in this case for those .AUX files.
