#281 [Add feature] zlib compress / decompress functionality
Dear Igor,
please add the feature to zlib compress files / decompress zlib compressed files.
There are merely few windows based programs out there for this task. All I could find for this, was some tool named "IP Tools by Erwan's Lab" and a tool programmed by some dude on majorgeeks forum.
I were trying to decompress an Android .ab Backup file created from ADB tool.
This backup file is basically an zlib compressed tar with 24 bytes extra header added in front.
If the file is not pure zlib, then ab header parser code is required in any case.
Just try to add support for plain zlib. If a file is not plain zlib, it should not be processed by 7zip.
€dit:
In case of .ab Backup file, the added header is to identify the backup version used to create the backup and wether it is a unencrypted zlib stream, or a AES256 encrypted one. The least case needs special handling. The first case can just be decompressed with zlib
