Google Chrome-file is not commonly downloaded and could be dangerous[Not jDownlo

[Multi-FEAST]

When I try and download a file from my site using Chrome I get the warning ...file is not commonly downloaded and can be dangerous. Several posts I have seen have overcome this by setting the file type and MIME properties.

One person comments "I added .zip as application/zip mime type and the warnings went away."

I was wondering how I create a file on Joomla jDownloads component and set the various file types such as

Content-Type: application/x-zip-compressed

Content-Type: application/zip

Hi
jDownloads presently has the zip mime type "application/x-zip".  The "x-" prefix of a MIME subtype indicates it is not registered with the "Internet Assigned Numbers Authority" (IANA). So that should be transparent. It is actually registered but that should not matter.

Using Chrome (Version 39.0.2171.65 m) a zip file with just jpg images was ok.  However using a zip file which contained an exe did give the "file is not commonly downloaded and can be dangerous" message on download.
So I changed the file extension of the exe to xxe and repeated.  This time Chrome had no problem.

So if you upload a zip with an exe file in it either you advise users to expect that message from Chrome, or you change the extension and tell users they need to change it back to exe.

Not a jDownloads problem.
