To revive a very old thread... Catalina apparently does things differently and no longer is happy with these ZipMBS files unless you do some more tweaks.
The solution is to properly set the "created by" version number field to &h0314: dim zipVersionMadeBy as uint16 = &h0314 // 03 = unix. 14 hex = 20 decimal = version 2.0 z.CreateFile(relativePath+name,zi,"","", zipFileComment, z.MethodDeflated, z.CompressionBestCompression, bUseZip64,bRaw, zipWindowBits, zipMemLevel, zipStrategy, zipPassword, zipCRC, zipVersionMadeBy, zipFlagBase) Perhaps this hint can go in the MBS documentation?
