What? Where is the 2/3 storage loss coming from in ReFS? I mean, I kinda get what you are saying if you are talking in a raid 6 operation, but not a single drive.

They just removed creating ReFS in all but Win 10 Enterprise and Pro for Workstations. You can still read write them, but will no longer be able to create the file system. Doubt MS is going to undo that bit, its likely they intend for this to be a enterprise only feature.

My guess is they wont do away with NTFS anytime soon

Also, regarding the topic...im having trouble wrapping my head around compression without penalty. There has to be some trade off otherwise why wouldn't it just be the default to compress everything since it doesn't have a penalty to it?

Its certainly interesting, I intend to read about it and dive into the utility itself, but it seems to me that if an OS had baked into it a way to greatly compress large volumes of content without a penalty they would want to advertise it and prior to now I'd never heard of this.

How is the result of using COMPACT with these options different from using NTFS compression?Some sources say that what COMPACT does is different from what the Compress contents to save disk space option in Windows Explorer does. Indeed, it looks like the difference is when Compress contents to save disk space enables NTFS compression that uses compression units (CU), COMPACT uses sparse files.

I don't know enough about the compression stuff to argue much more than that - but there is a link to MSDN on compression (below) used to make the arguments above. Don't have time to read them right now unfortunately.

https://blogs.msdn.microsoft.com/ntdebugging/2008/05/20/understanding-ntfs-compression/

I replied to your second post in an edit above, I don't know if you caught it before writing this one. In any case, I already understood the confusion around the matter and thanks again for the links and have some more REP+ thumb.gif.

In the first link you provide it's interesting to note that the poster is also confused as to the existence of compact in other Windows versions:
Quote:
Here's where you can use COMPACT to compress files and folders on NTFS. Despite what official documentation says about COMPACT
Quote:
The compact command, the command-line version of the NTFS file system compression feature,

COMPACT is not the command-line version of NTFS file system compression as it uses sparse files.


He links to the same Windows XP related documentation that the author of the utility in the OP does and in that regard, the description for what compact does from Windows XP all the way to Windows 8.1 is indeed correct, it's just that apparently there is no official documentation from Microsoft detailing the extra functionality that does things parallel to NTFS and thus when people look for what compact is and does, they end up with the documentation for the command as it works in Windows XP -> 8.1 and draw wrong conclusions about the functionality of the very same command in Windows 10.

TL;DR; the compact command exists in Windows XP, Vista, 7, 8.1 and 10, but the 10 version has additional, parallel to NTFS, compression algorithms available and that information is not documented in the Microsoft article that everybody, including the author of the utility in the OP, is linking to.

Ark SE went from a whopping 110gb to 61gb so it is def worth it.
For games on SSD's this is perfect especially big ones.

Only shaved 1GB off of GTA V for me, using the "best compression" option.

post #77 of 154
I don't like the idea of a sparce file system on principle, too much experiance with fragmentation, I suppose. However, this utility is an interesting option because when using the /EXE option it doesn't compress files added to the directory after the utility is run, eliminating fragmentation but increasing the total writes because compressed files are entirely rewritten in uncompressed form when they are edited. The compression process also increases total drive writes because it has to rewrite the entire file in compressed form.

Theoretically access times for very small files would increase but the load times for large files with large blocks of 0s would be much faster, loading an extra table of 0 blocks takes more time for small files but much less time for large ones.

However, large video files or other already compressed files do not have large blocks of 0s in them because they already use effectively similar compression methods that are actually more efficient but take much longer to encode (along with much more complex methods that are very different and take a relatively unbelievable amount of computation).

I think this is doing more compression than simply enabling a sparse file system, EXPRESS4K probably does extra, very fast, compression optimized for executables and libraries.

I would simply use the command line utility directly:

I see there's an option to mark a folder so that every file added afterwards will be automatically compressed, but it's grayed out for me. Trying to make sure it's checked so when a game has a patch on steam, that patch is automatically compressed as well. Anyone know how to circumvent this?

About as good as built-in Windows compression then. This tool doesn't seem to do much that couldn't be done already. Just go to you various drives, go to properties, and check a box:




It'll take some time to rewrite compressed versions of files, but it's definitely worth it.




Those 560GiB include 170GiB of video, by the way, which might as well be incompressible. File compression shaved off just 100MB. That leaves us with 390GiB of other files compressed to 328GiB, and discounting GTA V we have 320GiB compressed to 259GiB, which is a net 21% saving in disk usage (or effectively 25% more SSD for free) if used with appropriate files and typical games. GTA V isn't typical it seems; my Steam folder saves about 20% disk space this way, so the same as the rest of the drive.

That is coming in an update according to the dev on reddit.
