Detailed Description

Compressed File Input Stream. The class reads from a compressed file without explicitly uncompressing it. This is eachieved by running external 7ZIP program which uncompresses to standard output, which is then piped to TZipFl. The class requires 7ZIP to be installed on the machine. Go to http://www.7-zip.org to install the software. 7z (7z.exe) is an executable and can decompress the following formats: .gz, .7z, .rar, .zip, .cab, .arj. bzip2. The class TZIpIn expects that '7z' ('7z.exe') is in the working path. Make sure you can execute '7z e -y -bd -so <FILENAME>' Note: You can only load .gz files of uncompressed size <2GB. If you load some other format (like .bz2 or rar) there is no such limitation. Note2: For 7z to work properly you need both the 7z executable and the directory 'Codecs'.
