I always loved the feature of “Download all attachments” in Gmail.

Really usefull snippet, thank you !

@Ferhat BULUT : You could change content type header replacing "response.setContentType("application/zip");" with "response.setContentType("gzip");"

If you selected "GZip" in "Application Properties -> XPages tab -> HTML Generation -> Compression" property, system zips your file twice. You can download zipped file which is also GZipped (without file extension). It is confused me but I found the reason after a while :)
If you select "None" in related (writed above) property, you can download zip file with actual (attached in the document) file.
Anyway Thanks Naveen Maurya, It is good XSnippet.
