Controlling Paths of Files Added to Zip

When appending files to a .zip, it can be difficult to get the paths exactly as you want them. This example describes a way that you can control the path information when adding a single file at a time to a .zip.

require 'chilkat'

zip = Chilkat::CkZip.new()

success = zip.UnlockComponent("anything for 30-day trial")
if (success != true)
    print "Failed to unlock zip component" + "\n"
    exit
end

#  Intialize the zip object by calling NewZip.
zip.NewZip("myZip.zip")

#  Add a reference to a file on disk to the zip object.
#  (When appending files to a zip, the files are not actually
#  read into memory.  References to the file(s) are added.
#  When WriteZip is called, the referenced files are streamed in
#  and compressed to the .zip.)
saveExtraPath = false
success = zip.AppendOneFileOrDir("c:/temp/a/hamlet.xml",saveExtraPath)
#  For brevity, this example will not check the return status...

#  The saveExtraPath argument, if set, will cause the path information
#  passed in the 1st argument to be saved in the .zip.

#  To add "a/hamlet.xml", do this:
zip.put_AppendFromDir("c:/temp")
saveExtraPath = true
success = zip.AppendOneFileOrDir("a/hamlet.xml",saveExtraPath)

#  To add "temp/a/hamlet.xml", do this:
zip.put_AppendFromDir("c:/")
saveExtraPath = true
success = zip.AppendOneFileOrDir("temp/a/hamlet.xml",saveExtraPath)

#  The zip written here will contain hamlet.xml three times,
#  each with a different relative path.
success = zip.WriteZipAndClose()
