Tips to open LSP file

Can't open the LSP file? You are not the only one. Thousands of users face similar problems every day. Below you will find tips on how to open LSP files as well as a list of programs that support LSP files.

LSP file extension

File Category Developer Files

The LSP file is supported on 3 operating systems. Depending on your operating system, you may need different software to handle the LSP files. Below is a summary of the number of programs that support and open the LSP file on each system platform.

What is LSP file?

The LSP file has been categorized as Developer Files. Additionally, the Developer Files category contains 1205 of other files. Lisp Program Source Code Format is most often found on 3 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Linux, Mac OS, Windows. Alternatively, you can use 10 other programs. AutoCAD, Windows Notepad, Adobe ExtendScript, NotePad++ text editor will apply when it is not possible to use Clozure CL.

How to open LSP file?

An often recurring problem with Lisp Program Source Code Format is that LSP is not associated with the correct program file. Thus, when you open LSP, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the LSP file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Clozure CL

In this case, you should first verify that the Clozure CL application is installed on the computer. This can be achieved by typing Clozure CL into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open LSP files.

Step 2. Create association of Clozure CL with LSP files

If, despite the installed application, the LSP file does not start in the Clozure CL application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the Clozure CL application as the default for handling the LSP file.

Step 3. Update Clozure CL to the latest version

The fault may also lie with the Clozure CL program, it is possible that Lisp Program Source Code Format requires a newer version of the program.

Step 4. Check for the following problems with the LSP file

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the LSP file. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our LSP file. Sometimes virus-infected LSP files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the LSP file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular LSP file corruption.
The program can also signal the fact of encryption. The encrypted file LSP except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. Copying the LSP file to another location will fix the problem.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the LSP file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
