Tips to open LISP file

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

File Category Developer Files

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

What is LISP file?

The file in the LISP format belongs to the Developer Files category. In addition to this file, the Developer Files category includes 1205 related files. Lisp Source Code Format appears on 3 operating systems as a functional file. The file will work on Linux, Mac OS, Windows systems, unfortunately not on others. This file type can also be opened by 6 other programs. You can use TextMate, LispWorks, Adobe ExtendScript in case Clozure CL cannot be used.

How to open LISP file?

The most common problem when using Lisp Source Code Format is that a specific LISP is not associated with the program. Thus, when you open LISP, the program selection wizard or some other program starts. How to solve such a problem?

The first thing you should do is just "doubleclick" on the LISP 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

An often overlooked issue is to make sure that Clozure CL is installed on the computer. This can be achieved by typing Clozure CL into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file LISP.

Step 2. Create association of Clozure CL with LISP files

If, despite the installed application, the LISP 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 window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the LISP file with the Clozure CL program.

Step 3. Update Clozure CL to the latest version

If, however, after binding Clozure CL with Lisp Source Code Format there were still problems, you should update the program to the latest version.

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

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

Very often, the file may be size 0 or incomplete. Usually this applies to LISP files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our LISP file. However, remember that not every infected LISP file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the LISP file. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged LISP files.
The program indicates that the file is encrypted or corrupted. The encrypted file LISP 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.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. It is best to move LISP to a different directory.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file LISP to close. However, some background programs may block the LISP file while scanning. If the problem persists, restart the machine.
