Hint Details:

The Question was:


Is there a way to check a directory exists, from a XML job, like you can a file using <IfFileExists>?

The answer is:

Not directly. However, you can do a Directory Query, which returns the details of any files in a Directory and then just test for any records.  

If you search for all files matching '*.*', in addition to the file list, you will always get a single dot (representing the directory itself) and a double dot (representing the parent directory).

Thus an empty directory should always return 2 rows. See example below.

<Job autoclose="YES">
 <DirectoryQuery pattern="c:\temp\wibble\*.*">
     <MessageDialog text="directory exists"/>
     <MessageDialog text="directory does not exist"/>
