lszip

List ZIP archive's files without downloading the whole archive. Useful for large ZIP archives ( < 4GB for now, doesn't support ZIP64)

Requirements

• Python 3
• Web Server should support HTTP Range Request

Examples

List all files and directories in the archive

# python3 lszip.py http://example.com/zipfile.zip
0 : bios/
1 : bios/hello.txt 
2 : bios/hello2.txt
3 : tmp/
4 : tmp/bright.tmp
5 : newfile.txt 

Download hello.txt and bright.tmp

# python lszip.py --nolist --download 1,4 http://example.com/zipfile.zip

Download newfile.txt

# python lszip.py --nolist --download 5 http://example.com/zipfile.zip

Download directory tmp and all its contents

# python lszip.py --nolist --download 3 http://example.com/zipfile.zip

By default, this program will download files in current working directory but it will create folder trees if needed. This directory can be changed by using --cwd.
