Xbase++ Requires Chilkat v11.0.0+

Set Entry Filepath (in output Zip) when Zipping

Demonstrates how to set the path for the file entry within the .zip to something different than the path in the filesystem. Xbase++

//  When an absolute filepath is passed to AddFile, the path within the .zip
//  will be one of two values:  (1) just the filename part if saveExtraPath is 0,
//  or (2) the full absolute path, but made relative, if saveExtraPath is 1.

//  When a relative path is passed to AddFile, then saveExtraPath does not apply.
