Compresses a few files into a zip archive.
This is a simple function to compress a couple of files.
It does not preserve file permissions on Mac/Linux or other metadata.

And it may not work with non ASCII characters. We use UTF-8 on Mac/Linux/iOS, but there is no guarantee that this will work.

If you need more control over files being added, compression or error checking, please use example projects coming with plugin which use our other zip functions. Or use the shell functions and the zip command line tool.

Deprecated due to missing unicode support. Please use Archive.Compress for new projects.

This function requires a native path. Use Path.FileMakerPathToNativePath to convert a FileMaker path to a native path if required. If you like to have the user choose the path, you can use FileDialog functions.
For Server be aware that server has limited permissions and may not be able to access all files on a computer.
