Add file extension as a field available within the File group

Because this is a property available from the "files" database table which is provided by core, support for this would likely come from Views module itself because it provides integration with all supported core database tables.

Here is a patch. Later people could add a filter/argument

I dare say this should be called "extension" (i.e. "png" or "gif") instead of "file type" since that usually indicates mime type (i.e. "image/png" or "image/gif").

It sounds better, that's true.

And one minor details, this should just be // $Id$

+// $Id: $

The added space would probably prevent CVS from filling it in properly upon commit.

aaah i wondered why i had changed this snippet but i think this was just totally wrong.
Thanks for the review and this code style update.

+1 for this patch

+    'help' => t('The file extension of the file.'),

A bit redundant? "The extension of the file." would match the other help texts.
"File: File extension" could then also be "File: Extension".
But this is all nitpicking...

Other than that, the patch applies cleanly and works nicely.

Update

'help' => t('The extension of the file.'),

Yet another rerole

Awesome.

Committed to 6.x-3.x -- needs porting to D7.

Tried to port this, but couldn't figure out the new structure.
file_managed vs file_uasge and stuff...

At least I tried

Ping me on irc whenever you have some problems with porting patches

Ported and fixed.

I am having this problem. I want my users to be able to see the filename extension, but it isn't showing up. I read through this post hoping to find an answer, yet I am still coming up short. Anyone else had this problem with their extensions?
