Oh wait, these are being uploaded as .doc, .xls, and .ppt but those apps aren't 
on the machine where the downloading is happening.  Is that the case?

Hmm.  Sounds like what's missing is some sort of browser helper.  And 
LibreOffice is registered as the application that opens .doc, .xls, and .ppt 
files?  

Still, it would be useful to see if this improves if the MIME types for those 
Microsoft formats were delivered by the server.  It may be that Microsoft 
Office compensates for this problem when it is installed.  We'll know that if 
getting the server to use the correct MIME types doesn't help.

Subject: RE: [libreoffice-users] LibreOffice and Microsoft Office files - MIME 
type problem

This is a common problem with web servers.  

Browsers don't set the MIME type, they receive it in the response from the Web 
Server, along with the resource itself.  It is likely that the Web server is 
not set up to recognize that various file-name extensions correspond to 
specific MIME types and so a default is being used.  application/octet-stream 
is the safest default.

There's a secondary problem with regard to being able to *open* LibreOffice 
documents that are downloaded by a browser.  That has to do with associating 
the MIME type with an application on the receiving computer.  But first, you 
need the correct MIME type from the server.

The only way around, depending on how the file is downloaded, is to store it 
without opening it and then renaming it so it can be opened properly.  Not 
something your average user will deal with (especially if they don't have file 
exensions being show in Windows Explorer).

Most web servers have a way to be told what MIME type to attribute to 
particular filename extensions.  Someone needs to arrange with an administrator 
of the web site to set that up.

If the MSO document is uploaded directly to the server without being
opened in LO does your client have the same problem? I just want to
clarify if it is a problem with LO or possibly somewhere else. 

Do other browsers report the same problem when used or access the page?

Also, what version of LO are they using?
