DOS Directory File List

User Steps

These steps can be followed to output a printout of all files contained within a folder:

1. Open the DOS command prompt.
2. If necessary, change the drive location (example syntax: D: then press Enter)
3. Navigate to the folder location where you would like to write a list of the folders contained within it (example syntax: cd D:\Example\TUFLOW\model\grid then press Enter)
4. Write a text file listing the folder contents using the following syntax: dir > filename.txt

A text file called filename.txt will be written to the folder containing the files.

Example Application - Stitching Together ALS Data Tiles

This DOS file report is useful during TUFLOW modelling if ALS topography data has been provided in tile format for a catchment. In some situations over 500 *.asc files may make up a complete study area. Rather than stitching the data into a single topography dataset using GIS software, data layering within the TGC can be used to read each *.asc ALS tile into the TUFLOW flood model.

1. Open filename.txt in Notepad++ or UltraEdit.
2. Turn on column edit mode.
   • This is done in Notepad++ by holding in Alt prior to and during a selection
   • This is done in UltraEdit by holding in Alt+C prior to and during a selection
3. Select and copy the .asc file names.
4. Open the TUFLOW Geometry Control (TGC) File. Set the global model elevation to a value that is above all expected elevations with the topography dataset. the command is: Set Zpts == <value>
   We recommend using this value to check for any missing data or gaps between the ALS tiles after running the TUFLOW model for the first time.
5. Paste the .asc file name list into the TGC file.
6. Add the necessary command syntax and file path details left of the .asc file names using your preferred text editor ( Notepad++ or UltraEdit) in column mode.
7. After running the TUFLOW model for the first time, review topography check files _DEM_Z.flt and / or _zpt_check. Complete a query search for the global model elevation you set for the model. If the global model elevation value is present within the check file this represents a gap in your ALS topography dataset that requires correction or additional data.
