\**\ This pattern is often used in Copy Task for recursive folder tree traversal. Basically it means that all files with extension config would be processed from the all subdirectories of $(Services_Jobs_Drop_Path) path.

MSDN, Using Wildcards to Specify Items:

You can use the **, *, and ? wildcard characters to specify a group of files as inputs for a build instead of listing each file separately.

• The ? wildcard character matches a single character.
• The * wildcard character matches zero or more characters.
• The ** wildcard character sequence matches a partial path.
