    Yes, antivirus, maybe next time you have large amount of files to delete, you can disable real time protection.

    Yes, I could try it the next time...may be then a virus comes down. Or may be I will try it now while the deleting is running, still to delete about 1 million files.

    Yes, done, switched off the real time protection, but the speed appears to stay the same.

    As I said, just a thought. Copying files seems to be faster though.

    Yes, yes, a good thought, good idea, of course.

    When the real time protection is switched off? So, may be I should try it either.

    Yes, when switched off.

    But, I am wrong, TeraCopy appears to run much faster (FastCopy does not and the Win delete function also does not) when switching of Defender.

    Alight, so it seems, when transferring a lot of (small) files better turn off Defender (and may be let a virus get you).

    Terra Copy it is than ! I didn't use it for long time now and never have been doing too much of 1:1 transfer of large amount of files. I use backup SW mostly and let it simmer in the background as long as it needs to without much impact on overall performance.

    Possible, but unlikely. Disable your network adapter. Pull the cable. Turn off router. Not likely a virus could "come down", then.

    Has anyone asked you why there are over a million files to deal with? That really is quite a large number. Every time a file is added/changed/deleted/moved the $mft (master file table) has to be accessed. That's a million reads and a million rewrites of the MFT. If they are little small files, you likely have a lot of wasted space on your drive. The minimum allocated unit is 4K bytes. A little more background on how/why you have so many and the general purpose for doing so would help.

    I never counted my files backed up but I have about 2TB of MP3 files alone + another TB of pictures, I guess just those could end up as a sizable number of relatively small files.

    To delete files? For copying / moving I actually use synchronizing programs. Such a Win system is much too instable.

    and let it simmer in the background as long as it needs to without much impact on overall performance.
    Yes, a good procedure.

    Possible, but unlikely. Disable your network adapter. Pull the cable. Turn off router. Not likely a virus could "come down", then.
    Well, I must / want to stay connected to the Internet. Yes, may be unlikely. But when deleting / transferring about a day may be less unlikely.

    Has anyone asked you why there are over a million files to deal with?
    No, not until now.

    That really is quite a large number. Every time a file is added/changed/deleted/moved the $mft (master file table) has to be accessed. That's a million reads and a million rewrites of the MFT. If they are little small files, you likely have a lot of wasted space on your drive. The minimum allocated unit is 4K bytes. A little more background on how/why you have so many and the general purpose for doing so would help.
    Well, these files had been created by one or more recovery programs a few months ago, a partition was not accessible anymore. Now, respectively some months / weeks ago all of the data has been recovered and now after a waiting time (just to make sure) I since yesterday or so remove these files I do not need anymore.

    "That's a million reads and a million rewrites of the MFT." Of the entire MFT or of each single entry to be added to the MFT?
    "If they are little small files, you likely have a lot of wasted space on your drive." Yes, there are, why do small files need so many space?

    I never counted my files backed up but I have about 2TB of MP3 files alone + another TB of pictures, I guess just those could end up as a sizable number of relatively small files.
    I would say, such files are quite normal, respectively its size. Small files are about 0 byte up to some kb I guess.
