@ActionSaxon:
I don't think accessing a real folder this way is possible. You could try to use a plug-in (DLL) which accesses a real folder (files).
Also check out the download feature which allows to download f.e. a zip file which could be used in your program.
We will investigate if an option for accessing real files in Compatibility Mode is possible.
Please send me an e-mail about the details of your project. Maybe we can come up with an other solution.
