Very kind of take a minutes.
Yes, I find what you point.
And a one in CodeLoader compressFileNamed: aFileName in: aDirectory.
If I fileOut and later compress.
My question remains because I cann't figure out how using
RWBinaryOrTextStream as a fake file (as I could do in example I send).
As compressSources , that is the Dan's marvel what I asking if it is a
"general 1/3 compress solution" or maybe only works for large files.

So I remain trying until have success :)

Very thanks.
