Hi Alexander,
1.Can you please verify if you supported these extensions?
2.For the depend, do you support them or not ?
3.If the files not mandatories, do you used them in your conversion if there are exists?
4. For unsupported extensions , do you have plan to implement them and when ?
Thans in advance,
Extension Supported Meaning
.ifc No A .ifc file is an Industry Foundation Classes file, used in BIM (Building Information Modeling).
• Stores 3D building and construction data: geometry, materials, components, and metadata
• An open standard maintained by buildingSMART International
• Designed for interoperability between BIM software like:
• Autodesk Revit
• ArchiCAD
• Tekla Structures
• Vectorworks
.dwg No A .dwg file is a drawing file format used by AutoCAD and other CAD software.
• Stores vector graphics, 2D/3D geometry, annotations, and metadata
• Widely used in engineering, architecture, and construction
• Binary format developed by Autodesk.
.gdb Yes Use I nacse of dataset.
It’s actually a directory, not a single file.
Stores feature classes, tables, rasters, and indexes
.gdbindexes Yes A binary index file that stores attribute and spatial index information.
Appears inside a .gdb folder.
.gdbtable Yes Use in case of one table .
A .gdbtable file is an internal system file used by an Esri File Geodatabase (.gdb).
Stores the actual attribute data
(rows and fields) for:
• Feature classes
• Tables
.gdbtablex Yes Use in case of one table .
A .gdbtablex file is an internal index/auxiliary file used by an Esri File Geodatabase (.gdb).
Stores attribute index information for a table or feature class.
.atx Depend ??? An .atx file is an attribute index file used by Esri File Geodatabases (.gdb).
Stores attribute index structures for a field in:
• Feature classes
• Tables
It is not gis format, it’s additional files for format.
.horizon No Typically used in geological software (e.g., Petrel) to represent horizon surfaces.
Not part of Esri’s formats; “not directly supported” in ArcGIS.
.spx Yes An .spx file is a spatial index file used by Esri File Geodatabases (.gdb).
• Stores the spatial index for a feature class
• Used to speed up spatial queries, such as:
• Intersects
• Within
• Contains
• Map drawing and selection
• One feature class can have one or more .spx file.
.lpkx ??? LPKX – Layer Package
A layer package (.lpkx file) in ArcGIS is a file that contains both the layer properties and the dataset referenced by the layer. It allows you to save and share everything about a layer, including its symbology, labeling, field properties, and associated data. Layer packages can include multiple layers and can be directly added to maps by other users without requiring access to the original database or manual configuration of layer properties.
It is not gis format, it’s additional files for format.
.lyrx Depend??? LYRX – Layer File
lyrx file is a type of layerfile used in ArcGIS Pro to save and share the properties of a layer, such as its symbology, labeling, and other settings. It is an updated format compared to the older .lyr file used in ArcGIS Desktop.
It is not gis format, it’s additional files for format.
.mpkx No MPKX – Map Package
An ArcGIS Pro map package is a compressed file that contains a map and its associated data. It is designed to facilitate the sharing of maps and data between users or to archive work. A map package can include layers, their symbolization, labeling, table properties, and data.
.cpg Yes A .cpg file is a code page file for a Shapefile.
• Stores the character encoding for text fields in the .dbf attribute table
• Ensures non-ASCII characters (like accented letters, symbols, or non-Latin scripts) display correctly in GIS software
• Typically contains a single line specifying the encoding, e.g., UTF-8 or ISO-8859-1
.dbf Yes A .dbf file is the attribute table for a Shapefile or other legacy GIS vector formats.
• Stores tabular data (rows and columns) associated with geometries in .shp
• Each row corresponds to a feature
• Columns store attributes (names, IDs, values, etc.)
• Follows the dBase format, a legacy database format.
. prj Yes A .prj file is the projection file for a Shapefile or other GIS dataset.
• Stores the coordinate system and map projection information
• Ensures GIS software knows where the data is located on the Earth
• Text-based and usually written in Well-Known Text (WKT) format.
.sbn Yes A .sbn file is a spatial index file used by Shapefiles.
• Speeds up spatial queries (e.g., “intersects” or “within”) for Shapefiles
• Works alongside .sbx:
• .sbn → spatial index
• .sbx → supporting index data
• Optional but improves performance in GIS software like ArcGIS.
.sbx Yes A .sbx file is the supporting spatial index file for a Shapefile.
• Works together with .sbn:
• .sbn → main spatial index
• .sbx → supporting index data
• Speeds up spatial queries and rendering in GIS software like ArcGIS
.shp Yes A .shp file is the main geometry file of a GIS Shapefile.
• Stores the geometry (points, lines, or polygons)
• One of several files that together make up a Shapefile dataset
• Not usable by itself
.shx Yes A .shx file is a Shapefile index file used in GIS
• Stores the index of geometry records in a Shapefile
• Allows fast access to features without scanning the whole file
• Part of the Shapefile trio:
• .shp → geometry
• .dbf → attributes
• .shx → index
