The bil file extension is associated with ESRI ArcView GIS software.
The bsq, bil, and bip formats represent ways of storing 24-bit images in memory or on disk.
The initials stand for band-sequential, band-interleaved-by-line, and band-interleaved-by-pixel, respectively.
These image formats are also sometimes called "band-interleaved", "row-interleaved", and "pixel-interleaved", respectively.
Use ESRI ArcView to work with the *.bil files.
Possibly can be converted to other GIS formats or perhaps exported as normal images.

Record marked as obsolete and not updated for a long time.
The bil extension is also used for some sort of source file in LISP programming language.
Lisp (or LISP) is a family of computer programming languages with a long history and a distinctive, fully parenthesized syntax.
Originally specified in 1958, Lisp is the second-oldest high-level programming language in widespread use today, only Fortran is older. Like Fortran, Lisp has changed a great deal since its early days, and a number of dialects have existed over its history. Today, the most widely known general-purpose Lisp dialects are Clojure, Common Lisp and Scheme.
Use compatible tools to work with *.bil files.
Probably cannot be converted to other formats.

The file contains raster data representing a satellite image in an 8-bit GIS tape format. Its 8-bit depth provides 256 possible pixel values, which may represent image brightness or another measured value depending on the SPOT dataset.
This format is mainly encountered in older satellite-image and GIS data collections. A compatible GIS or remote-sensing application may also require the accompanying dataset information to interpret the image correctly.
Open the .bil file with GIS or remote-sensing software that supports SPOT satellite imagery. If the file came with metadata or other companion files, keep them together so the application can determine the image properties and geographic information.
A general-purpose image viewer may not recognise this format or may not display it correctly.
Use compatible GIS or remote-sensing software to export the satellite image to a more widely supported raster format, such as GeoTIFF. GeoTIFF is preferable when the geographic information must be preserved.
PNG or JPEG can be used for a visual copy, but these formats may not preserve the original image measurements or geographic information. Conversion requires the image's accompanying dataset information where applicable.
