File Extensions

  1. Wassup guys,
    The other day I just noted that every filename for all files saved in my hard disk has its associated extension indicated at the end of the filename unlike is the usual case where the extension doesn’t appear; for example if it’s a text document, the extension “.txt” appears at the end of the file name or “.avi” for a windows media video file and “.doc” for a Microsoft office word file. I also have to be keen not to delete the extension during the renaming of files or else the file would be unusable afterwards. What could possibly be the problem here?

    Its just a setting you need to alter.
    Open an explorer window.
    Tools > Folder options > View(tab)

    ps...not figured out how to paste the image directly into the message yet. :eek: Anyone care to enlighten me?

    If the OP isn't familiar with altering settings in windows, why on earth would you point him toward something as potentially damaging as registery editing...???

    Mind you, having the file extensions visible is a Good Thing! This way you cannot be tricked into running a program that has a text file icon for example.
