---- Introduction

ComZip is a shareware of data compression/encryption. Its current version (x64) supports large data window up to 0.5 GB. The performance depends on the actual RAM size. ComZip may have better compression ratio than WinRAR and 7-zip, and it may be faster than 7-zip.

---- Compression Command Line

Usage:
zip.bat <compressed file> <original file path> <config file> <index file>

Example:
zip.bat c:\test\test.cz c:\test\test.txt cz.ini index.xml

---- Decompression Command Line

Usage:
unzip.bat <compressed file> <decompressed file path> <index file>

Example:
unzip.bat c:\test\test.cz c:\test\cmp index.xml

---- Config of Data Window Size

You can modify the parameter "cache" in the config file "cz.ini". And you can use odd values, for example, 371 MB, 1235 MB, etc.
But if the value exceeds the capacity of RAM, the system will use the virtual memory. This will slow down the speed rapidly. Thus the data window is limited by the actual RAM size.
System RAM size and the recommended value:
RAM>=2GB: cache=60
RAM>=3GB: cache=124
RAM>=4GB: cache=252
RAM>=6GB: cache=508
RAM>=8GB: cache=1020
RAM>=16GB: cache=2044
RAM>=32GB: cache=4092
RAM>=64GB: cache=8188
RAM>=128GB: cache=16380
