(PureBasic) 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.

    ; (When appending files to a zip, the files are not actually
    ; read into memory.  References to the file(s) are added.

    ; 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:
    CkZip::setCkAppendFromDir(zip, "/temp")
    ;  The saveExtraPath argument, if set, will cause the path information
    ;  passed in the 1st argument to be saved in the .zip.     But the path in AppendFromDir is
    ;  not added to that path saved in the .zip.     If there is a path in AppendFromDir then the
    ;  path in the 1st argument must be relative, not preceded by a drive or \.
    saveExtraPath = 1
    success = CkZip::ckAppendOneFileOrDir(zip,"a/hamlet.xml",saveExtraPath)

    ; To add "temp/a/hamlet.xml", do this:

    saveExtraPath = 1
    success = CkZip::ckAppendOneFileOrDir(zip,"temp/a/hamlet.xml",saveExtraPath)

    ; The zip written here will contain hamlet.xml three times,
    ; each with a different relative path.
