Can I send folders (with sub-folders) with MASV?

MASV preserves the folder structure of whatever files are sent

Yes, as long as you select the Add Folders button, all sub-folders, folder hierarchy, and naming conventions are kept intact. The only exception is that empty folders with no files in them are not sent through.

Your recipient will be able to download the entire package as a zip and once extracted will see the folder structure you added. 

The functionality is limited by some browsers. We recommend using the latest version of Chrome or Firefox for best experience.
