I know I can perform workflow actions on files based on age but the current workflow module doesn't allow me to specify any file attributes.

If there is a folder with a mix of files, I may only want to compress or delete txt files or log files.  There should be a way to specify the actual file name and type using wildcards.

Examples:

Delete files older then 7 days with the file extension txt and name "*" (wildcard) located in c:\logs

Delete files older then 7 days with the file extension log and name "errror*" located in c:\logs
