| Hi,
I'm trying to extract a several files from a cabinet file without MS
cabinet.dll.
Is there any way to compute the compressed offset of a certain file in a
folder of a cabinet file so that I don't have to extract all prior files of
that folder?
Thanks, Martin

No. Use more folders. Use one per file if you like. Find the sweet spot
between compression lost and improvement in random access time. Or you could
modify something like libmspack to store all decoded bytes as it works,
rather than pass them on and discard.
