What is LLI file?

The file with the extension LLI is the 3D Image Files file type. Additionally, the 3D Image Files category contains 622 of other files. AutoCAD Landscape Library Format is supported by 2 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Mac OS, Windows. It is recommended to use AutoCAD to handle this file. This is a program created by Autodesk, Inc.. Alternatively, you can use 1 other programs.

How to open LLI file?

An often recurring problem with AutoCAD Landscape Library Format is that LLI is not associated with the correct program file. This causes the file LLI to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

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

The first step is to check if the computer has the AutoCAD program installed. The easiest method is to use the system search engine by entering the program name AutoCAD in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support LLI files.

Programs to open LLI file

Remember to download programs supporting LLI files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of AutoCAD with LLI files

If, despite the installed application, the LLI file does not start in the AutoCAD application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. 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. The "always use the selected program ..." field will set the AutoCAD application as the default for handling the LLI file.

Step 3. Update AutoCAD to the latest version

If, despite the association of the AutoCAD program with the AutoCAD Landscape Library Format file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the Autodesk, Inc. website and install the latest version.

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

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. Usually this applies to LLI files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file LLI or the program directory. As a result of the scan, sometimes it is not possible to recover LLI files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the LLI files changes over time. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular LLI file corruption. The easiest way to restore the file is from a backup or by contacting , but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted LLI files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. If possible, you can try to move the LLI file to another location.
This can happen on a file that does not support multiple access. In this case, the LLI file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the LLI file while scanning. If nothing helps, please reset the device.
