What is an LSP file

LSP files mostly belong to AutoCAD by Autodesk. The LSP file extension is primarily associated with Lisp, a family of computer programming languages. This file format is known as Lisp Program Source Code format as the LSP files contain source code files written in Lisp language. These files are also known as high-level programming language assembly codes.

• Main Usage: The primary content of an LSP file associated with Lisp is the plain text program code that can be executed while using Lisp interpreter. LSP files may contain a single component of an application or a stand-alone program or parts of a larger software project. As Lisp language is widely used in areas of Artificial Intelligence (AI), Symbolic Processing (SP) and Natural Language Processing (NLP), LSP files are utilized a lot in these areas.
• Associations:
• • Liquid Audio Player List File: Liquid Audio Player by Geneva Media also uses LSP file extension for its playlist files.
  • LANsurveyor Poll List File: LSP file extension is also used with the poll list files created by LANsurveyor, a program that monitors up and down status of network nodes.

How to open LSP files

You need a suitable software like AutoCAD to open an LSP file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your LSP file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a LSP file directly in the browser:. Just drag the file onto this browser window and drop it.

LSP file format details:

To find out what program is needed to open LSP files, you need to determine the file format. The file format can be deduced from the file extension and the signature. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. If there are problems opening a file, you must first determine the file format used. Below you will find our evaluation of the LSP files:

An LSP file includes very many different file formats. The file formats most commonly found in LSP files are:

• 15% of all LSP files start with the bytes (defun , which are crucial for this file format. The contents of these files are easily readable with a text editor. The files are on average 1 KB in size and range from 100 bytes to 5 KB. The file type is relatively new. The files contain the following words: defun c, setq and command.
• 4% of all LSP files are AutoCAD Protected LISP code files. These files contain neither text nor words, but only data. A typical file size is 6 KB. The files contain the following words: AutoCAD PROTECTED LISP file.

All other LSP files (81%) have no consistent format, often, for example, Printer and XFS. These files sometimes refer to head, acaddoc, length, table, total or text. If you want to find out which format your LSP file belongs to, just click on the button "Choose your .lsp file to view".
