In each of the .shp, .shx, and .dbf files, the shapes in each file correspond to each other in sequence (i.e., the first record in the .shp file corresponds to the first record in the .shx and .dbf files, etc.). The .shp and .shx files have various fields with different endianness, so an implementer of the file formats must be very careful to ...
The file format is the native spatial data storage format for Autodesk GIS programs MapGuide and AutoCAD Map 3D. As of 2014 SDF format version SDF3 (based on SQLite3) uses a single file. Prior versions of the format required a spatial index file (SIF), with an optional key index file (KIF) to speed access to the file.
The OGC GeoPackage standard specifies a set of OGC member approved extensions in Annex F. Additional (vendor-specific) extensions may also be added by following the rules for GeoPackage extensions, however doing so can impact interoperability. GeoPackage was designed to be as lightweight as possible and be contained in one ready-to-use single file.
This was most common from the 1970s through the early 1990s, because GIS software developers had to invent their own geometry data structures, but incorporated existing relational database file formats for the attributes. For example, the Esri Shapefile format includes the .dbf file from the DOS dBase software.
KML files are very often distributed as KMZ files, which are zipped KML files with a .kmz extension. The contents of a KMZ file are a single root KML document and optionally any overlays, images, icons, and COLLADA 3D models referenced in the KML including network-linked KML files. The root KML document by convention is a file named "doc.kml ...
This mismatch was not possible when the census TIGER files were available in ASCII format that was topological unlike shapefiles. The Census Bureau has made the data available through WMS servers. [4] The data forms a base for OpenStreetMap in the US, and also was used for the initial import of US map data into the Waze navigation system.

In this case the files should be manually deleted. Normal temporary files have the following file name extensions: .TDA Temporary database file.TIN Temporary index file.TMA Temporary Map File; When using a database table such as Oracle Locator or Spatial, if the data is downloaded to the local machine, the temporary file name extensions are:
