Cannot get the information about WinFLP.wim image

Post by ohault »

Hello,

I have just noticed that old WIM files are not currently supported by wimlib.

e.g. the WIM file from Windows Fundamentals for Legacy PCs

C:\>wiminfo WinFLP.wim
[ERROR] "C:\Users\OHA\Documents\Testwim\WinFLP.wim": Header size is invalid (96 bytes)
ERROR: Exiting with error code 17:
The WIM header was invalid.

ImageX is able to mount this file and 7-Zip will open the file, see below

As far as I know, the old WIM format was only used in Vista pre-releases. This is the first time anyone has asked for it. So I don't think it's important to add support for it.

But it would be probably easy to add, right?

Probably not; it would require reverse engineering the old file format, implementing support for it (probably including read-write support since people would want that too, right?), testing with an old version of Windows, and writing tests.

I don't see why this would be worthwhile to add, given that it was phased out almost 15 years ago. And wimlib has never supported it and this is the first time anyone has ever complained.
