Win10 2004...disk space.

50GB drive, with 8GB remaining. After the update there was 5GB
remaining, the windows.old directory was 4.34GB. The *.old directory
was automatically deleted...Message: "Your running low on storage,
the previous version was deleted. No change is space remaining on C:\
still setting at 5GB.

And that represents really high compression, how
ever that was done.

Hi,

I was going to respond a few days ago when you were wondering if you'd
have enough disk space to do a feature update to 2004, and say what
others have said...insert an external whatever type of drive (USB HDD,
USB flash...), and all would work just fine, because I have a small SDD
and have been through this successfully. But, I see you already got 2004
installed. Anyway, here's my recent experience with installing 2004 on a
32 GB SSD. This was on 6/22/20.

The laptop I did this on is an HP 13" with a 32 GB SDD that I bought in
early 2016 ($230) just to see what Windows 10 was like. I think it came
with version 1507. It's been successfully updated through every feature
update (version upgrade) ever since. But, at some point, I had to delete
stuff on the SDD to make room for feture updates. Finally, just deleting
stuff was not enough to make room for feataure updates, and Windows told
me I had to insert an external device in order to install feaature
updates. This happened to me when installing 1909, and again when
installing 20014.

I didn't ask for 2004 (I didn't press 'check for updates'), but it was
presented to me, and I knew that at some point I'd have to say stick it
to me. So I did.

The install of 2004 started around noon on 6/22/20, and looks like it
completed around 8:24 pm the same day. I didn't attent the whole thing,
but watched as much as I could.

I've included a link to some screenshots of the process going from 1909
to 2004. It's interesting that it looks like I gained 1.13 GB, even
though Windows.old is still on the SDD. Also, there's a new folder on
the SDD called Windows.older, that contains seven folders, all of which
are empty.

I have no idea what this folder, Windows.Older, is all about, because
before I initiated the 2004 updatee, I checked to see if there was a
Windows.old (let alone an Windows.Older) folder on C:. There were
neither.

Folder $WINDOWS.~TMPWindowsOld.win was created on the USB flash drive I
used for extra space. It's about 3.3 GB.

By the way, the colors settings on my display were changed to white, from
an orange-ish. All other settings seem, so far, to be intact.

Glad you got 2004 installed.

And that WIM would be an example of a way to achieve high compression.
As the WIM has several compression levels, and the top level is as
powerful as the 7Z one. These are miles better than stuff like LZO,
but creating that 3.3GB file also cost some CPU cycles and time.

That WIM file has a date stamp of 8:24PM, which is the last file, or
thereabouts, that was created. Installing the update, once it was
downloaded, took from around noon to a little past 8 pm. I didn't attend
the goings-on the entire time, so can only tell by the latest time stamp
on any files created.

I wonder if the WIM file, on the USB flash drive is needed if one were to
go back to 1909, or if C:\Windows.old is all that is needed. Just
wondering.

What is "LZO"?

There are a whole bunch of compressors out there.
Too many to keep track of.

Some are termed "lightweight", which means they
provide very little compression. For example, one
does such a poor job, that if you "compress" a text
file with it, you can still read the text file.
It makes hardly any modification to the file at all.

"compression comparable in speed to DEFLATE compression"

You use stuff like that, when you want "a little bit" of
compression, but don't want to slow things down too much.

Whereas 7Z is very slow to compress. And to compress an
entire hard drive, costs about $1 of electricity. For once,
you can "price" a computer operation :-) It's not often
that something uses enough power, to have you sitting down and
working out the cost of it.

With 7Z Ultra, the machine I'm typing on can only process 2-3MB/sec
or so. Think how long it would take, with such a gutless machine,
to do a whole disk drive.

This is why we have $3000 processors with 64 cores. So it
still "takes all day to do it".

To see more of the LZ ones, I tried a Google and found this chart.
It's like a bunch of people needed a hobby :-)
