Filter files using regular expressions

This flow demonstrates how to filter files based on the file names containing a date. The format of the date being checked is dd-mm-yy and can be placed anywhere in the file name.

This flow is compatible with: LightSWITCH, FullSWITCH, PowerSWITCH

Information

All files dropped in the input folder will be checked and will be moved over the connection only if their file name contains a date of the format dd-mm-yy. All other files will be rejected by this connection.

The regular expression used to filter on date is the following: .*(0[1-9]|[12][0-9]|3[01])[-](0[1-9]|1[012])[-](\d\d).*
