Hi,

by peeking around in "Deep into Pharo" I thought that

|�� zf fr |
fr := 'I:\SAS_Projekte\project.egp' asFileReference.
zf := FileSystem zip: fr.
zf store open.

should be used to open a zip file programmatically. That fails with
"ZnInvalidUTF8: Invalid utf8 input detected"

Looking at MCMczReader, it skips the FileSystem API completely.

In FileSystem-Tests-* I find DiskFileSystemTest and MemoryFileSystemTest, no ZipFileSystemTest to see how it's supposed to be done.

Did I do it wrong? Or is FileSystem not yet "finalized" in that area?

Best regards,
�� Markus
