Property Value

Type: Usual
A string representing the extension defined to this file specification.

A string representing the extension defined to this file specification. The extension may have been assigned explicitly or as part of a longer file specification (assigned either as an instantiation parameter or as part of the file name or full path). When accessing FileSpec:Extension, the requested extension is returned with a leading period. When assigning FileSpec:Extension, you can specify an extension with or without a leading period. Assigning a NULL_STRING (or NIL) to the extension means that the extension is unknown or unspecified; the various functions and objects that use the file specification to locate the file uses whatever default extension applies to them.
