Hi Juraj,

The file streams opened in a memory file system are not polymorphic with the ones in a disk file system :(.

Can you open an issue and assing it to me? I'll work soon on making all of them work and yield binary streams.

I can successfully use ZipArchive like the following

-=-=- zip := ZipArchive new. { 'file1.txt'. 'file2.txt'. 'file3.txt' } do: [ :eachFile | | member | member := zip addString: eachFile, ' contents' as: eachFile. member desiredCompressionMethod: ZipArchive compressionDeflated ]. file := FileLocator temp / 'archive.zip'. zip writeTo: file writeStream. file. -=-=-

What I should do to make it work while using FileSystem memory?

-=-=- zip := ZipArchive new. { 'file1.txt'. 'file2.txt'. 'file3.txt' } do: [ :eachFile | | member | member := zip addString: eachFile, ' contents' as: eachFile. member desiredCompressionMethod: ZipArchive compressionDeflated ]. fileSystem := FileSystem memory. file := fileSystem root / 'archive.zip'. file writeStreamDo: [ :stream | zip writeTo: stream ]. -=-=-

There is "Improper store into indexable object” as it tries to store a number in ByteString. Thanks! Juraj
