I had a problem with importing an XAR running xwiki-enterprise-1.1-milestone-3 and my WinZip program didn't recognise the XAR as zipped file like other XAR files. Is this a known problem? Has it been fixed in the latest releases? Is there anyway to recover the data in this 'corrupted' XAR?Could the Import/Export facility be develop to provide proper backups (as Confluence does) so you don't have to attach an XAR file to restore as a backup?Regards,Richard
