File Explorer' view options has the ability to show both
- Hidden system files(the option is named 'Hide protected operating
system files). Default setting is hidden(not checked, not shown)
and
- Show hidden files, folders and drives. Default setting is hidden(not checked, not shown)
Note: Not all folders or folders of files in File Explorer have hidden protected operating system and/or hidden files.
i.e. depending upon the selected folder and contents, the number of
items shown for folders and files in File Explorer may or may not change.

File Explorer, and look through the list of possible headings, Attributes is one of the
options. I just tried turning it on for an obscure folder, and it looks as if A - archive
- is still turned on by default for new files, the others not. (IIRR, some old DOS
functionality toggled A _on the original_ when a file was copied, as part of some way of
saving you from having to copy again a file that had not changed - hence it standing for
"archive" [meaning "this file hasn't been archived"].)
R (which I think of as "read-only" rather than "Read/Write", but that's really just
semantics) is still used by some softwares; it usually only shows its head when you try to
save something you've been working on, and the software says it can't, and brings up the
save window for you to type in a different filename. I'm pretty certain that any file on
(or copied from) a CD or DVD will have the R bit set, which seems fair enough.
I _think_ S was used when you were making a boot floppy (!) - was the command "sys a:"? -
and resulted in files with that attribute being included.
I don't know if there are any more - I think not, as I think they used a four-bit space
somewhere (in the filename or directory maybe?). Obviously lots of file information _is_
now added, but a lot of it is in metadata in the file itself (I use WinAmp to edit it for
MP3 files, VLC for video files [doesn't work for all types], and IrfanView for image
files; plenty of other utilities can edit them too, including File Manager itself for some
of them). I think there's also some information in the sort of "shadow" copy of the
directory information that NTFS uses ("journalling" is it?); I've never learnt that
properly - Paul knows. (As with everything!)

Old compression or single-file-EFS-encrypted files, show in

is only supported on 4K cluster NTFS file systems. (Modern Windows only allows 4K cluster C: drives, and no longer tolerates 64KB clusters on

Bitlocker or FDE encrypted disk drives, are another level of encryption separate from the application of EFS.--

Obviously this takes four bytes per file. In systems before NTFS, did it only take one, or half? Where - in the directory alongside the filename (something like the drwxrwxrwx of UNIX [and I presume Linux])?>

The Macrium compressor is not much of a compressor.
That's because it can't afford to burden the user
with a slow backup. I don't know if it is stated somewhere,
exactly what compressor it uses.
And Macrium won't "use all your cores" either. It's
not that kind of program.
The Windows 7 Backup, is potentially "the fastest backup going".
But when you go to restore, does it always work ? Dunno.
I don't think the Windows 7 Backup program uses checksums,
and there is no "Verify" for the VHD/VHDX containers it collects.
I've never spotted any metadata that suggests otherwise.

Indeed! I remember once _restoring_ (for a friend) from a Macrium DVD took an unconscionable time to _boot_ (half an hour maybe? - With long pauses when it didn't seem to be doing anything), though once it _had_ booted, the actual restore was fine andnot too long.>

PaulJohn (G.)
The Macrium ReScue OS, is stored as a .wim file, and it is
loaded as a RAMDisk. when booted, the OS partition is called
X: which leaves the letter C: available if it were needed to
some purpose. It should be a "straight read of 300MB of material",
followed by the usual Microsoft code load behavior.
If you aren't doing anything with the media of importance,
you might notice that ejecting the Macrium OS media, affects
the session not-at-all. That's because the OS is now in the\
RAMDisk X: set up on your machine and references to the boot
.wim are no longer needed..
To restore an MRIMG, I suspect the program starts by examining
some indexes it stored at the end of the session. It has to load
some of that info, before the restore-proper can begin. This is
important if you are restoring and changing the size of the partition
as you restore (making it smaller).
If the MRIMG data being restored is on optical media, that's a
pretty slow source. Once the restore gets going, the reads should
be sequential.
IDK, I don't know if I'm patient enough, to allow a thing like that
to proceed without some optimizing.
I did once test a Windows 7 Backup to DVD media, and the Microsoft
burn utility did not have code for erasing re-writable media. I was
flipping out the DVD, and erasing it with ImgBurn, then popping it
back in so the Microsoft backup code could do its thing. I think it
took me two hours and four pieces of media, and I was fit to be
tied by the time I was finished.
Today, I would think you would need a title similar to(-:
Mother Theresa for attempting such a stunt :-) So so slow.
I could row a boat faster than this.

Sure. But it is safe. Even if some daft software stored data in empty sectors. There are some.
