Filename altered for allowed file extension [#1491348]

My allowed file extension are txt msi mui.msi mst exe

If I'm uploading a file named "foo.1.0.0.Installer.MUI.msi" it get's renamed to foo.1.0.0.Installer.MUI_.msi and I have no idea why. Extension msi is allowed and I also tried mui.msi. Nothing works.

Note, file names cannot change.

The message is For security reasons, your upload has been renamed to %filename. from file_save_upload().

Essentially, a file extension is defined as that part of the filename which follows the final '.'. The '.' is not a supported character in the "allowed file extensions" in the field manager settings, (although nothing prevents you from adding it.)

If you change your "Allowed file extensions" to "txt, msi, mst, exe" (eliminating "mui.msi") then "foo.1.0.0.Installer.MUI.msi" will be uploaded without a name change. (works for me).

Some reference:
function file_munge_filename in file.inc, where it processes the filename to parts: $filename_parts = explode('.', $filename);

I've reviewed all settings again, see below. Your test results seems not correct. I guess you have not used the filename example I provided. See the node edit page:
