    Displaying folder extensions?


    I'm not entirely sure where to put this because it's not really related to any problems that I'm having or any broken apps, but more just a usability issue with Explorer itself.

    Does anyone know how to have folder extensions displayed? I find it a little ridiculous that the upgrade creates a Windows.old folder, but folder extensions are hidden by default. It's even more inane that if you accidentally type a period when renaming a folder, it will then take on that extension, which will subsequently disappear and no longer be editable.

    Enabling view system files and folders as well as hidden folders and enabling showing of extensions for known file types does nothing. The only way I've found to view the extension that a folder has assigned to it is by right clicking and viewing its properties (Type: Folder (.randomextension)), or by viewing it in the command prompt.

    Check view, then check box in ribbon, show file extensions may help.

    No, none of the conventional methods seem to do anything. You can check and see for yourself by making a new folder and just attaching any extension to it.

    I must be missing something here, files have extensions but the last time I checked folders didn't?

    That's mostly true, there aren't many situations in Windows where a folder would gain an extension, and in past versions of Windows adding a .whatever would "change" the extension, but only to the extent of what the properties window says the file type of the folder is. What I've noticed with Windows 8 though, is that it actually adds an extension to the folder, then somehow hides that extension from everything other than the command prompt and properties window.

    Lets take the folder that the upgrade assistant creates with your old windows folder. It puts your old windows directory into C:\Windows.old, which you would assume would appear as such, but instead you get two folders in the C drive named Windows. If you right click on each of them to view properties, one of them will read "Type: Folder" and the other will read "Type: Folder (.old)"

    This is reproducable by adding .whatever to any folder, but only the first time. The first time you add an extension, it applies it to the folder then hides it, the next time you try to add an extension to the same folder, the folder behaves as you would expect (just appending .whatever to the folder name).

    Um, if a folder has an extension its not a folder its a file? Sounds more like a glitch. Adding .old to the folder name just adds .old to the folder name. It's still not a file extension. It looks like Windows 8 treats it like a descripter when you go to properties. The thing is, it says Folder (.old) not File (.old). So my advice, for what its worth, is don't add .something to your folder names.

    It definitely sounds like a glitch, you are correct that something with an extension is a file rather than a folder. There is something in Windows 8 that is assigning extensions to folders, and is treating them as such. The extension becomes hidden and there is no way to access it other than the command prompt (you can't even edit it from the properties window) that I'm aware of (this is what I was looking for in the OP).

    I mean sure, your advice is sound (however dumb it is that Windows 8 takes issue with appending a .whatever to your folder names), but that's not what I was looking for. I want to know how I can get it to either a) stop treating .whatever as an extension when it's in a folder name, or b) display the "folder extensions"

    I don't know what to tell you. I did a clean install so I don't have a Windows.old folder. As a test I created one and the .old part didn't get hidden. I also created a test.old.bmp folder. The .bmp didn't get hidden either. I have windows set to "hide extensions for known file types".

    I'm gonna have to ask a friend of mine who went through the upgrade rather than a clean install as well, and see if he can reproduce it.

    Did you rename the folder to add .old, or did you name it test.old from the get go? What did the properties window say for file type?

    I did both, the properties says Folder (.<whatever is after the last dot>)
