FileExists

This function can be used to test the existence of a file.

An example would be something like:

«SetV('fileName',concat(Directory,'\ExtraTemplate.xdtpx'))»
«If(FileExists(GetV('fileName')))»
«MergeTemplate(GetV('fileName'))»
«End(if exists)»

This will construct the name of a file in the XpressDox variable named ‘fileName’, and, if the file exists, issue the MergeTemplate command for it.  Without the test for existence, if the file did NOT exist, the MergeTemplate would fail with an error message.
