By default, many file types are blocked, including file
types that are treated as executable by Internet Explorer. Each Web application
maintains a list of blocked file types that is based on file name extensions.
Please refer the following file extensions that are
by-default blocked in SharePoint 2010 [Recommended by Microsoft]
I would like to tell you that this is not a SP limitation
and we can allow any file types to be uploaded in SharePoint but not
necessarily a great idea. Storing .EXE files in SharePoint can cause some
serious security issues. Just imagine if a user wants to upload a .exe with a
friendly name like "Gtalk.exe" but it’s really a virus - not good!.
SharePoint is definitely not the place to store everything,
.EXE files being one of those things.
My suggestion: If we are intending to have .exe files
(or scripts etc.) stored in a SharePoint system, then at least put them inside
zip files and allow .zip files to be uploaded rather than .exe files. This will
mean that while the .exe files are still available, more effort will be needed
to start them. Future prospect: Many benefits, Less
pain J
SharePoint isn't a file share, it's web application.
Considering internal as well as
external point of view: If you are accessing these internally only, we
could keep them on a file share and just link to them from the SP site. This
will execute outside of the browser instance in this case, but won’t work for
outside users, unless you publish file shares via something like UAG (Unified
Access Gateway).
