Windows 10: How to accelerate deleting of files / folder?

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.

Yes, a good procedure.

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.

No, not until now.

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 would say, such files are quite normal, respectively its size. Small files are about 0 byte up to some kb I guess.

 

NTFS
512 bytes/sector
4096 bytes/cluster
Even one byte over that will take another sector's space so in theory a 513 bytes file will use up 1024 bytes of space on disk. There's more to it of course, like space in MFT etc. so you may end up wasting a lot.

 

So very small files obviously can use more space than slightly bigger files than those very small files, very strange.

No, no, actually I should not waste such space because I now have deleted these files. But now, after having deleted all of these files the recycle bin is shown (almost) empty:




But when I press SHIFT+DEL (the recycle bin on the screenshot being marked) the deletion is shown to be prepared and at the end there will be shown over 1 million files:








What is wrong?

A another program shows the recycle bin empty and not containing about 256 GB of data:

 

After deleting all files try using this program: Download UnCleaner - MajorGeeks it's amazing how much more of space it can release.

 

Alright, thank you very much. There does not appear to be a portable version of it.

 

I use it every other day or after uninstalling programs (with Revo Uninstaller) or deleting lot's of files. It also cleans up a lot after doing disk cleanup for upgrade and setup file.

 

OK, good to know, never heard of it
