WMS:File Extension

Here is a table of file extensions and their functions:

Extention	File Name	Description
.1	1 FILE
.94	94 FILE
.OCX	ACTIVE X CONTROL
.PDF	Adobe Acrobat Document
.EXE	APPLICATION
.DLL	APPLICATION EXTENSION
.ASC	ASCII Grid Files	WMS can import ARC/INFO® ASCII grid for use as a background DEM. Since it is a simple file format, other digital elevation data can be formatted in the same way and then imported into WMS using the Import Grid command in the DEMs menu.
.BASIN	BASIN FILE
.BSN	BSN FILE
.INI	CONFIGURATION SETTINGS
.CSE	CSE FILE
.DAT	DAT FILE
.DBF	DBF FILE
.DDF	USGS DEM
.DEM	USGS DEM
.DLG	Digital Line Graph	The DLG to Feature Arcs option allows a Digital Line Graph file to be imported and points connected into a series of arcs. USGS DLG files, like DEMs, can be downloaded via the Internet and are available for many parts of the US.
.DSS	HEC Data Storage System files	This format is used for importing and exporting time series and XY series data to and from HEC-RAS, HEC-HMS, and other HEC software.
.DTED	DTED Grid
.DTM	This file format is no longer supported. If you are interested in using this file format, contact the WMS developers.
.DWG	CAD Files	CAD files may also be imported and then converted to feature objects, TINs, or simply used to enhance the display of a project.
.DXF	CAD Files
.ERR	ERR FILE
.EX_	EX_ FILE
.F01	F01 FILE
.FAC	FAC FILE
.FBC	FBC FILE
.FDR	FDR FILE
.FLT	FLT FILE
.G01	GO1 FILE
.GDM	GDM FILE
.GGD	GRASS ASCII grid
.GMT	GMT FILE
.HC1	HC1 FILE
.HDR	NED GRIDFLOAT or BIL Header	This is the format that should be used from the USGS's National Elevation Dataset (NED). The default at this site is Arc/Info grid, but you should modify your request to the grid float format. The BIL format can also be used.
.HLP	HELP FILE
.HTM	HTML DOCUMENT
.ID	ID FILE
.IMG	IMG FILE
.INP	INP FILE
.ISR	ISR FILE
.ISU	ISU FILE
.JGW	JGW FILE
.JPG, JPEG	JPEG Image	Jpeg image format file.
.JPGW	JPGW FILE
.JPW	JPW FILE
.LAS	LAS FILE
.MAP	LINKER ADDRESS MAP
.LNP	LNP FILE
.LOS	LOS FILE
.LSF	LSF FILE
.MAN	MAN FILE
.MAT	MAT FILE
.MDB	MDB FILE
.PKG	MICROSOFT DEVELOPER EXTENSION
.DOC	MISCOSOFT WORD DOCUMENT
.COM	MS-DOS APPLICATION
.BAT	MS-DOS BATCH FILE
.NET	NET FILE	ARC/INFO TIN - This particular format saves node (vertex) coordinates, a list of edges and a list of triangles, making it possible to restore the TIN topology in WMS exactly as it was in ARC/INFO
.O01	O01 FILE
.LIB	OBJECT LIBRARY
.OCR	OCR LIBRARY
.OUT	OUT FILE
.P01	P01 FILE
.PDN	PDN FILE
.PRJ	PROJECT FILE
.PTP	PTP FILE
.R01	R01 FILE
.RAS	RAS FILE
.SBN	SBN FILE
.SBX	SBX FILE
.SDAT	SDAT FILE
.SHP	Shapefiles
.SHR	SHR FILE
.SHX	SHX FILE
.IDX	SQL SERVER REPLICATION SNAPSHOT INDEX SCRIPT
.STO	STO FILE
.SUP	WMS Superfile	Besides the tools in WMS for editing data imported from shapefiles, a special extension for ArcView has been created which allows you to create the outlets, streams, and basins themes, reorder streams, rename attributes, and then export to a WMS/ArcView super file which will allow you to open all three themes by importing the super file. This extension is placed in the wmshydro directory (under the main wms directory) when installing WMS. It is also available on the WMS website and has a separate document describing its usage. In order to be activated in ArcView you must move the extension file (*.avx) to the Ext32 directory found under the ArcView® installation directories.
.TBL	TBL FILE
.TDAT	TDAT FILE
.TDN	TDN FILE
.TXT	TEXT DOCUMENT
.THY	THY FILE
.TIF	TIF Image Data	A TIFF file can be imported and registered so that it appears as a "backdrop" in WMS or mapped to TIN data when shading.
.TIN	TIN FILE
.TRE	TRE FILE
.WDM	.WDM FILE
.WPR	WMS PROJECT FILE
.XY	XY FILE
.XYZ	XYZ Data	Choosing this option allows you to read in a space-delimited file containing x, y, and z coordinate values. The Triangulate command in the TINs menu can then be used to create a TIN from the xyz data. The file must be space delimited in order for WMS to import it.
