Anyway, it shouldn't be to hard writing such a tool as a native program. 

Maybe not for you!!!!! I can't program for toffee!

BTW - that would be great if you are offering. I believe that I have also sparked some interest from Erwan.l on the reboot.pro forums.

Very quick file extract test. Using following command -

java -jar re7zip.jar -t=cab -a=http://download.microsoft.com/download/3/8/B/38BBCA6A-ADC9-4245-BCD8-DAA136F63C8B/adk/Installers/a32918368eba6a062aaaaf73e3618131.cab -e=fil3a96a4ae37b2d6a62b94d42e1126dde0 -o=fil3a96a4ae37b2d6a62b94d42e1126dde0

Some output from the cmd (including time of the extracting/download) -

blah
blah

Percentage :  99 Reading  27892006 of  27971974 bytes

Done. Downloaded in 0 minutes and 16 seconds.

(extracted) File size of fil3a96a4ae37b2d6a62b94d42e1126dde0 = 26.6 MB
I haven't checked what this file actually is yet. I'll report back in later.

Well, if such a program will be useful I might program one.
But there is the problem with compression blocks.

java -jar re7zip.jar -t=cab -a=http://download.microsoft.com/download/3/8/B/38BBCA6A-ADC9-4245-BCD8-DAA136F63C8B/adk/Installers/a32918368eba6a062aaaaf73e3618131.cab -e=fil3a96a4ae37b2d6a62b94d42e1126dde0 -o=fil3a96a4ae37b2d6a62b94d42e1126dde0

That file is the first in block 4, so It will be very quick, though not with my internet connection :(
But loading another file in the same block, needs to download all other files in that block before that file.

Example

java -jar re7zip.jar -t=cab -a=http://download.microsoft.com/download/3/8/B/38BBCA6A-ADC9-4245-BCD8-DAA136F63C8B/adk/Installers/a32918368eba6a062aaaaf73e3618131.cab -e=fil3ae9b0835c65f44ed796fafe895b87c2 -o=fil3ae9b0835c65f44ed796fafe895b87c2

Both needing the same time.

Done. Downloaded in 1 minutes and 33 seconds. :ph34r:

 

@erwanl

yes getting the information from the cabinets is no big problem, but the decompression is more tricky.

Indeed, getting the blob is rather easy but handling  decompression will be trickier and this specially since we may encounter different formats : MSZIP, LZX, etc ...

If I may help, which langage are you using for GWT? (I am a delphi/FPC dev).

GWT is written in PureBasic, but it only uses WinAPI for everything to be so small.

I think that such a program would be useful, although probably not to a large number of people. It's a specialist tool and in the days where many have relatively fast internet connections and unlimited bandwidth most users will probably just download the whole file for convenience.

A good user case! :whistle:

I am not familiar with compression blocks - how much additional data are we talking about here to download the needed file?

28 MB additional download is needed for this 1 KB file.

Ah. Now that's not so good! Is it likely that this downloading of unneeded data could be avoided if a native tool was developed? Or the functionality added to GWT?

As for these cab files with solid compression, no there won't be much saving.

@JFX - are older version of GWT available for download. The current version appear hardcoded to download the Windows 10.0.16299 version of DISM and dependencies. Whilst the need is not widespread, there may be some instances where it would be useful to download other Windows 10 versions. I believe that these may be coded into some of the previous GWT releases?

I recently wondered the same... :-)

(it's a small world)

I know you don't like the "buggy as hell" 16299, JFX uses wimagapi from 15063 in his great WinNTSetup (I use imagex.exe from that version as well for UUP direct apply).

Whilst some versions might be better than others, I don't really like any of them as they all seem to give mixed result and random partially unmounted wims.  I miss the old imagex.exe from Vista days - it was great fun playing around with it back then. That version may also have been buggy as hell too - I haven't used it for years.

These days I'm more inclined (storage space permitting) to use wimlib to apply an entire boot.wim rather than running mount and unmounts operations. Depending on the size of boot.wim and the system hardware it doesn't feel like it takes much longer. Only time I need to do this is when applying a package. If only some genius could trace which minimum set of files need extracting from boot.wim so that DISM can be used to successfully apply a package to this smaller file set - without the need to fully apply the contents of boot.wim. And entirely removing the need to mount the image.
