7-Zip displays information about compression method in File Manager (and in console with the -slt switch). I have some questions and feature requests regarding that information.
7-Zip does not display any parameters except for Dictionary size for LZMA2. Why? These parameters are displayed for LZMA streams (if they differ from the defaults).
7-Zip does not display the number of Fast bytes used to create the compressed stream. Is this value stored anywhere in the headers? (I guess it is not, so if I am right, it is not possible to re-create it from an archive.)
What does the number after an encryption method mean? For example, I have the following line:
16 means dictionary size 216 bytes, but 19 does not evidently represent AES-256.
It would be interesting to see another information (at least by explicitly specifying the -slt switch): LZMA2's chunk size, archive header's compression parameters, uncompressed and compressed sizes of BCJ2 additional streams.
Igor, if it is not very difficult, please let 7-Zip display such verbose information (whichever does not require additional computation).
Thank you for the clarification.
