Description Michael Ochmann CLA 2014-08-27 09:24:49 EDT 
When exporting a project with empty directories as ZIP archive and re-importing that ZIP archive again, empty directories are gone. Looking into org.eclipse.orion.internal.server.servlets.xfer.ClientExport it seems that the write method only adds zip entries for files but not for the directory structure.
In contrast, ClientImport handles imports of ZIP archives with empty directories perfectly well.

Since export/import in Orion is commonly used for transfering projects between workspaces or between Orion and some offline tools I would have expected that the directory structure is preserved. Eclipse for example exports empty directories in ZIP archives.

Is that behavior of Orion on purpose?

A fix for that issue would be fairly simple:
