File extension

[HL]

Can anybody help?
Whenever I need to save any attachment from Outlook or any program, I have
to type the file ext. like .pdf or .doc after the file name otherwise the
default is ALL FILES. If I forget to type the ext. it will save as unknown
and the next time I open that file, it
cannot identify the file ext.
