How to open LON file?

The most common problem when using Aquaterra Profile Data is that a specific LON is not associated with the program. This causes the file LON 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 LON 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 Aquaterra

The first step is to check if the computer has the Aquaterra program installed. This can be achieved by typing Aquaterra into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file LON.

Programs to open LON file

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

Step 2. Create association of Aquaterra with LON files

If the application is or has been freshly installed, but the LON file still does not use the Aquaterra program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. 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. 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 Aquaterra application as the default for handling the LON file.

Step 3. Update Aquaterra to the latest version

If, however, after binding Aquaterra with Aquaterra Profile Data there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the CGS plus page and install.

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

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

Very often, the file may be size 0 or incomplete. Usually this applies to LON 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. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file LON or the program directory. As a result of the scan, sometimes it is not possible to recover LON files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the LON file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular LON file corruption. You can restore the file from a backup or use CGS plus help.
The program can also signal the fact of encryption. The encrypted LON files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
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. If possible, you can try to move the LON file to another location.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes you have to wait for the session to the file LON to close. However, some background programs may block the LON file while scanning. If the problem persists, restart the machine.
