A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .e00 Files
E00 files are plain text files that store ESRI Arc/Info export data.
They are used to package geospatial information into a text format. This format stores both geometry and attribute data for maps, making it portable between GIS applications.
- Main purpose: Exporting spatial data from ESRI Arc/Info systems.
- Additional uses: Archiving and exchanging map data across different platforms.
- Software support: Open or import these files using GIS applications such as ArcGIS, QGIS, or Global Mapper.
- MIME type: text/plain, which means the file is encoded in a readable text format.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is an .e00 file?
An .e00 file is an ESRI ArcInfo Interchange file used to transfer coverage data, including map geometry and attributes, between different GIS systems. It formats complex spatial data into a single ASCII text file for easier portability and archiving.
How do I open an .e00 file?
You need specialized Geographic Information System (GIS) software to view the map data properly. Popular programs include ESRI ArcGIS Pro, QGIS (free and open source), and Global Mapper. While you can open it in a text editor, you will only see raw code, not the map itself.
Can I convert an .e00 file to a Shapefile (.shp)?
Yes, converting .e00 to the standard ESRI Shapefile format is common. In ArcGIS, you can use the conversion toolbox, while QGIS allows you to import the .e00 layer and then right-click to "Export" or "Save Features As" a Shapefile.
Why does the .e00 file look like text when opened in Notepad?
The file relies on the text/plain MIME type, meaning it stores data in human-readable ASCII characters rather than binary code. However, the text structure is specific to ArcInfo software, so while Notepad can open it, the contents will look like lists of coordinates and attributes rather than a visual map.
Is the .e00 format still used today?
It is largely considered a legacy format, replaced by modern Geodatabases (.gdb) and Shapefiles (.shp). However, many government agencies and historical archives still store older map data in .e00 format, requiring conversion for modern use.
How should I configure my server to serve .e00 files?
Since these are text-based export files, the correct MIME type configuration is usually text/plain. This ensures that web browsers and clients recognize the file as a standard text stream during transfer.
Does QGIS support .e00 files directly?
Yes, QGIS uses the OGR library to read various vector formats, including ArcInfo Coverage files. You can typically drag and drop the .e00 file directly into the QGIS interface to load the vector layers.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
