Re: saving folders
It's enough to select parent folder and export it. All sub-folder will be exported too. Use HTML format for exporting, this way you will be able to open it even using regular web-browser on any device/platform.

saving folders
Hello,

I have multiple sub-folders in my personal folder. A few of them have a hundred or more folders. How can I export select sub-folders. Is there a way to export them to an Ipad and read them there and store them.

Thanks,

Jeff
