wimlib

wimlib only supports mounting WIM files on Linux, not on Windows.

Thanks, this doesn't actually compile with libfuse3 though. First there is the error: In file included from /usr/include/fuse3/fuse.h:19, from src/mount_image.c:46: /usr/include/fuse3/fuse_common.h:802:4: error: #error only API version 30 or greater is supported 802 | # error only API version 30 or ...

I don't think this is needed. If you are executing the wimlib-imagex binary, you can pretty easily log the command line yourself, and redirect the output to a log file yourself.

In the WIM file format, the solid compression type(s) and solid chunk size(s) are separate from the main compression type and chunk size. So in this case, to match a DISM-created /compress:recovery file exactly you'd need to explicitly change the main compression type to LZMS and the main chunk size...

Please explain your problem more clearly. I don't speak German, I don't know exactly which of the 5 images you are comparing to what, I don't know what software you are using to view the WIM images and what values it's showing you. Can you provide a minimal reproducer using the wimlib-imagex command...

wimlib supports LZX window size up to 2 MiB. You simply need to use the options I suggested. But as I said, WIM uses independently decompressible chunks, which can result in worse compression ratio than CAB at same LZX window size, even though wimlib's LZX compressor (given a high enough compression...

CAB has an advantage in compression ratio because it doesn't divide the data into independently decompressible chunks, whereas WIM does. But if you don't need independently decompressible chunks, you might as well use LZMS compression with its much larger chunks. I don't believe DISM in Windows 7 ev...

Why it is using the weakest LZX:15 compression instead of LZX:21, like in WinCab? Because that's the only LZX setting that's compatible with Microsoft's WIM software (WIMGAPI, DISM, ImageX). If you don't mind your archives being compatible with wimlib only, you can use: wimcapture --solid --solid-c...

The changes are always summarized in the NEWS file that's included in all the downloads. For v1.13.1 there was just a single bug fix: Version 1.13.1: Fixed a crash or incorrect output during LZMS compression with a compression level greater than 50 and a chunk size greater than 64 MiB. This affected...

I don't think I can figure out the remaining problem(s) anytime soon without being able to reproduce it myself. I don't have much to go on, and I have limited time. So for now I went ahead and released v1.13.1 with the fix I mentioned, so at least one bug is fixed. I don't suppose there's any chance...
