How can I display extensions in windows explorer in windows 7? There used to be an option in XP, but I can't find it in Win 7.

file extensions? – slotishtype Jun 20 '11 at 13:10
Like .exe, .pdf etc. The long descriptions of a file type are totally not readable for me, I just want to see .h rather than "Microsoft Visual C++..." (the rest being truncated). – Grzenio Jun 20 '11 at 13:13

1) Press Alt (or Organize>Layout>Menu bar and check it)

2) Select Tools -> Folder options -> view -> Files and Folders (un-click hide extensions for known file types).

You can accept an answer in 7 minutes - this web site is getting more annoying to use every day :( – Grzenio Jun 20 '11 at 13:17
@Grzenio +1 ... I hear ya bro. – slotishtype Jun 20 '11 at 14:08
@Grzenio At least you accept answers. I have only been here 20 days, and there are already people, whose questions I won't bother with. So thank you for your diligence. – KCotreau Jun 20 '11 at 14:36
@Grzenio By the way, instead of holding down ALT, you can also click Organize>Layout>Menu bar and check it. you will then be able to find it like old XP. – KCotreau Jun 20 '11 at 14:39

Try (in an Explorer Window) Tools > Folder Options > View Tab > Untick "Hide extensions for known files types".
