See more Zip Examples

Demonstrates how to iterate over the files and directories in a zip archive by index. Ruby

require 'chilkat'

success = false

#  This example assumes the Chilkat API to have been previously unlocked.
#  See Global Unlock Sample for sample code.

zip = Chilkat::CkZip.new()

success = zip.OpenZip("qa_data/zips/sample.zip")
if (success == false)
    print zip.lastErrorText() + "\n";
    exit
end

numEntries = zip.get_NumEntries()

entry = Chilkat::CkZipEntry.new()

i = 0
while i < numEntries
    zip.EntryAt(i,entry)
    #  Note: In the ZIP file format, it is not required for a ZIP file to contain explicit directory entries. 
    #  However, explicit directory entries can be included for convenience and compatibility with certain ZIP file processing tools and software.
    #  An explicit directory entry in a ZIP file is an entry that specifically represents a directory, rather than a file. 
    #  It usually has a directory name with a trailing slash (/) and zero-length content.
    if (entry.get_IsDirectory())
        print i.to_s() + ": " + entry.fileName() + " (directory)" + "\n";
    else
        print i.to_s() + ": " + entry.fileName() + "\n";
    end

    i = i + 1
end

#  Sample output:

#  0: aaa/ (directory)
#  1: aaa/pigs.json
#  2: bbb/ (directory)
#  3: bbb/base64Cert.txt
#  4: bbb/sub1/ (directory)
#  5: bbb/sub1/brasil_cert.pem
#  6: bbb/sub2/ (directory)
#  7: bbb/sub2/penguins.gif
#  8: bbb/sub2/starfish.jpg
#  9: hamlet.xml
