Files with the file extension TXT can be SWMM routing interface files, or generic text files.

If Wave determines that the file is not a SWMM routing interface file, it attempts treating it as a CSV file.

Generic text file

Generic text files are treated as CSV files.

SWMM routing interface file

Wave detects a SWMM routing interface file by checking for the string SWMM5 at the beginning of the file.

The format is described in the SWMM format description information.png.

Example (flow only):
