Hide File Extensions Mac

That preference, when set, causes the Finder to ignore the hidden-extension attribute on files and show the extensions anyway. You still have to set the attribute on the files, which you can do by opening the Finder Info window on the selected file and checking the Hide extension box. Word for Mac 16.11.1 document extensions (.doc and.docx) are. Show all Filename extensions is not the opposite of 'hide all file name.

Hi I am looking for a way to get OS X to hide ALL file extensions on the entire computer. I don't know why, but they really annoy me! I liked OS 9 and earlier because they didn't have them, and including them in OS X seems like a step backward to me. Wherever I can I simply don't save with file extensions (MS Office still retains this ability), and most applications will still open their files if you delete the file extension, but I do have a number of applications that require a file extension (such as OmniGraffle Pro), and it is very laborious to have to go through every file in order to hide the file extension. Is there some kind of master setting that you can apply to a volume in order to hide every file extension in it? There is no way to hide all extensions.

Some extensions cannot be hidden even on a case-by-case basis. This is a security feature, since some hidden extensions could disguise the true nature of a file. Try naming a file 'picture.jpg.app'. You will not be allowed to hide either extension.

It would be an obvious security risk if you could. However, most applications allow you to hide the extension on a file at the time you save it, and in my experience, most default with the Hide Extension option checked. OmniGraffle does, and I don't see why OG Pro would be different. LSRW, You may already know this but as a general caution: files with hidden file extensions are sometimes stored on servers (common business practice). In some cases: doing so results in the file metadata being stripped from each file, rendering them useless.

I saw this on another thread here just yesterday. Business employees were uploading files with hidden extensions to their file storage server. When the files were retrieved, they were unable to open or read any of them. It was proved that the metadata had actually disappeared and had not just remained hidden somehow. Hi All, I have found this tutorial that partially solves the problem. It is a quick way to hide the extensions of all files that have them in a given folder and the folders inside it, using automator. Sound effect apps.

It does not hide the extensions of any file you add to the folder subsequently, and you can not apply it to a volume or a home folder. It is more of a labour-saving tool than an actual solution, but it is vastly better than having to get info for every single file. As the author of the tutorial notes in his video, this is an option that apple could fix by just adding one more check-box to the finder preferences window. Or better still they could have just left things the way they were before and not introduced them in the first place. Does anyone even know what they are for anyway? (Apart from to annoy you with a random bit of text at the end of a filename that you didn't place there.). Does anyone even know what they are for anyway?

They are there in order to play nice with Windows. Extensions are the only way Windows has of telling one file type from another. So instead of sending a Windows user a TIFF called named Robin, you send them Robin.tif. Without the extension, Windows would have no clue what to do with the file.

The Mac OS is also slowly working its way away from the old Type and Creator codes. At some point in the future, it's likely the Mac OS will also rely on extensions only. In order to keep files with the same extension straight, so an Illustrator.eps doesn't open in Photoshop, or visa versa, OS X files also carry the new Uniform Type Identifiers metadata. OS X still relies on file extensions too and to a really undue degree. Yes, if there are no Type and Creator codes in the resource fork, it then has to rely on the extension.

Without either, OS X reverts to its version of 'generic unknown' and displays it as a Unix executable. As a result snow leopard relies on file extensions even more than leopard did (as there is often nothing else to rely on). There is something very wrong about this. I read a couple of years ago that Apple was going to move away from Type and Creator codes, though I don't remember why. Something to do with old encoding or something.

Being also a longtime DOS and Windows user from way back, file extensions seem completely normal to me. Apple Footer.

Lecture Notes - File Extensions File Extensions A file extension is a group of letters that appear as a suffix to a file name and help you determine the type of file and what programs can be used to open that specific file. By default, Windows 7 and Mac OS operating systems hide all file extensions. When you design a website, it is crucial to know what files you will be uploading or downloading, so you need to set your computer to be able to see the file extensions. When you don't see file extensions, it is also a big security risk since a common technique virus authors use is disguising an.exe file as.jpg,.doc, or.txt when it's actually an executable file (.exe) making you run and install a malicious program. The bad guy may send you a virus 'pictures-of-janet.jpg.exe', if your file extension was hidden, you would not realize the file was.exe since you only see the name of the file as 'pictures-of-janet' and once you realized what you did, it's too late.
