This still depends on the program. In pegasus the full filename with
extension will appear.
Anyway, there is a way to cause those filenames to appear with their
extensions even in Windows.
Customly, the following files will not appear with their extensions even if
you set to see extensions:
.lnk - Link (Desktop/Start Menu Shortcut)
.mad - Access ShortCut Module
.maf - Access ShortCut Form
.mam - Access ShortCut Macro
.maq - Access ShortCut Query
.mar - Access ShortCut Report
.mat - Access ShortCut Table
.pif - Piffile (Personal Information File MS-DOS Shortcut to MS-DOS)
.shb - Shortcut into a document
.shs - Shell Scrap Object
.url - Internet Shortcut
Here is what to do in order for those extensions to appear:
Run Regedit.
Search for the phrase "NeverShowExt" (without the quote)
in HKEY_CLASSES_ROOT for the various file types, and rename the
appropriate instances from "NeverShowExt" to "AlwaysShowExt".
Comment: If both the String Value "NeverShowExt" and
"AlwaysShowExt" appear for the same file type, the "NeverShowExt"
will hold.
