- Fast: Remove the extension by renaming the file without the .xyz extension in the Finder.

Hide file extension via rename
I don't think that removing the extension is desctructive. If you remove the extension in the finder, it will just turn on the "Hide Extension" flag for that file. The extension is still there (which you can see in Get Info).
Not for me
I have 10.3.9, so maybe that makes a difference, but I just got info on a TIFF file. It showed the full file name with extension and had a "hide extension" checkbox (unchecked). I closed the info window, removed the ".tif" extension in the Finder and got info again. This time the file name was displayed WITHOUT an extension and the "hide extension" checkbox was gone entirely.

It can indeed affect the Mac's ability to open a file. I recently wanted to remove the .jpg extensions from a couple of hundred digital camera files on a CD (to make contact sheets for a university thesis - long story). Renamer4Mac did the job just fine, but Photoshop would no longer recognise the files as something it could open. The only solution was to run a Batch process to open each file in Photoshop, then save it again - after that, removing the extensions did no harm (something to do with resource forks, or whatever they're called these days? Geek input required...)

I bet you could have selected all the images, selected Get Info for them all (Info Inspector is probably the best bet or you'll end up with a window for each if the number of files is low), and change the Open With selection to Photoshop.

Photoshop is very strict when it comes to dealing with filename extensions. Having the wrong extension is even worse than having no extension. I think the programmers were being lazy, because a peek at the first several bytes of data in an image file will usually reveal what type it is (jpeg, tiff, etc.)

Setting 'Open with...' to Photoshop: I thought of that - it didn't work. Opening, resaving with the 'Batch...' command, and then removing the extension, did.
not destructive
the original post said "rename in the Finder", and by that it meant "not in the Get Info window". If you remove the extension in the Finder, it's still there, but hidden. Rob, maybe you could edit to clarify?

OK, I actually tested some of this stuff. Removing the extension (from the icon's name or in get info) DOES remove the extension. The only way to hide it is in an Info/Inspector window, or set it globally via Finder's advanced prefs.

Ahh yes, thank you for explaining it. I have show all extensions set. I never knew all this crazyness existed when you turn that pref off.

That has not been my experience. I have a test file here, "test.png". I change its name to "test". In the Finder it no longer has an extension, but when I go into Get Info, the name is still "test.png" with the "Hide extension" box checked.

(I was replying to bdog, not bpotato. I think bpotato has got it right: the Finder will only let you delete the extension if it is not a known extension.)
Hide file extension via rename
Why do it? I can't think of a reason, except in the case I described above - to get a Photshop contact sheet without the extensions in the filename, where merely hiding them did not work. I believe if the files had been created with a Mac Photoshop in the first place, remving the extension would not have caused a problem.

This is one of the reasons why I'm not sad to see Avie Tevanian leave Apple. This feature shouldn't be necessary in the first place.

This only works if there isn't another known extension in the filename after your deletion (like ".pict", ".zip", whatever). If there is, the finder will expect that the new extension will be the extension you wished and ask for a confirmation, then proceed with deleting the old extension (that is, your old extension is not hidden, but effectively deleted).
Hide file extension via rename
I like file extensions just fine. I like knowing at a glance what kind of file it is, and I like the fact that files I hand off to a PC [I must work with both] don't need any special attention from me.

Anyone know a way to tell Finder to automatically hide the .webloc extension on files created from URLs dragged from Safari's location field (and other places)? Is there some way to run "Hide extension" with Automator?

Finder Preferences / Advanced /Nope. Give me some credit for already trying some that obvious (long ago). :-)

Uhh, something that obvious.

If you usually drag them to the desktop, then you could attach a folder action to the desktop to automatically hide the extension of newly created webloc files.
This also works, perhaps better
At least it's non-destructive and maintains platform cross-compatibility
With the Developer Tools installed, run
and that should take care of it. I use this often enough that I have an alias, called "moyel," in my .cshrc.

Sweet. That's all I need to quickly hide those pesky .webloc extensions. Thanks! |
