I've found LHA decompression has some issues with AmigaOS Lha archives: they are only partially extracted to Windows 11 (on the left the extraction results):

It seems to automatically ignore "unknown extensions" files (e.g. *.guide) in the extraction process...

Here is the LHA archive for you to test: ProTracker4Export.lha

Windows 11 24H2, BZ Pro registered 7.37

Hello, this is Bandisoft.

- Some files in the LHA archive are hidden. Open File Explorer, select View > Show, then select "Hidden items."

- Open the archive with Bandizip, select View (Alt+V) > > Column > File Attributes to check in advance which file has the hidden attribute.

Stupid me I didn't check that! You're right!

I forgot it was a common issue back in the days where some Amiga DOS files used +h as 'hold and modify' attribute (to keep small exe cached in memory...) incorrectly for some files, converted as 'hidden' under Windows/MSDOS.
