Re: JScript - is a file of a known Type?

I'm not sure I understand. Do you mean you want to
find out if it's a registered file type? That would be
in HKCR. If OK6 is registered there will be a key
HKCR\.ok6

| In Windows Script Host, given a File Object with properties including
| Name and Type, is there a direct guaranteed infallible way in
| JScript/VBScript to find whether the file is a known Type?
|
| Examples :
|
|        FILENAME                TYPE                            KNOWN
|
|        LONGFILENAME.HTML       Firefox Document                Yes
|        SEAKFYLE.OK6            OK6 File                        No
|        SEAKFYLE.ZIP            Compressed (zipped) Folder      Yes
|        SEEK.$$$                $$$ File                        No
|        SEEK.BAT                MS-DOS Batch File               Yes
|        SEEK.VBS                VBScript Script File            Yes
|
| For those, it suffices to test, case-dependently, whether the Extension
| appears as a word in the Type : if it does not do so, then the file must
| be a known Type.  But the converse is only reliable if one can be sure
| that a known extension cannot ever, in any natural language, occur as a
| word in the corresponding Type string.
|
| Consider the possibility of a default browser being called "View Your
| HTML", for example - unlikely, but possible.  Or that of a file with
| extension "File".
|
| The application is SEAKFYLE, via
| <http://www.merlyn.demon.co.uk/programs/32-bit/00index.htm>, using
| Options X3 and X4. The current code is in a paragraph currently starting
| at Line 281 :
|
|  if (Eggs == 3 || Eggs == 4) { S = Item.Path
|    S = S.substring(S.lastIndexOf(".") + 1) // Extn
|    if (Eggs == 4 ^ new RegExp("\\b"+S+"\\b").test(Item.Type)) return }
|
| Eggs 3 returns for unknown types; Eggs 4 for known ones.  In JScript,
| the token ^ means "Exclusive-Or".
