Note that you might lose files if you have several files matching the mask DocumentA*.
But if you are sure there is only one file, here is a way to implement this with FileMove :
- File To Dir: d:/temp
- File From Dir: d:/temp
- File Includes: DocumentA*
- File Target Mapper: DocumentA*=DocumentA.txt
- File Target Mapper Type: regexp
An alternative is to set the Physical Name of the file with a Variable or a Parameter. See this article for more :
