How to open C18 file?
The most common problem when using Dassault Systemes Catia V4 Sequential is that a specific C18 is not associated with the program. Thus, when you open C18, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.
The first thing you should do is just "doubleclick" on the C18 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 CATIA
An often overlooked issue is to make sure that CATIA is installed on the computer. The easiest method is to use the system search engine by entering the program name CATIA in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file C18 with CATIA. Later in this article you will find a list of programs that can open C18 files.
Programs to open C18 file
Remember to download programs supporting C18 files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of CATIA with C18 files
If, despite the installed application, the C18 file does not start in the CATIA 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. 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 select the desired program. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the C18 file with the CATIA application.
Step 3. Update CATIA to the latest version
The fault may also lie with the CATIA program, it is possible that Dassault Systemes Catia V4 Sequential requires a newer version of the program. In this case, use the Dassault Syst?mes S.A. website or update the program from the application.
Step 4. Check for the following problems with the C18 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:
The affected file may be 0 KB or smaller than expected. Usually this applies to C18 files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the C18 file that we want to open. As a result of the scan, sometimes it is not possible to recover C18 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 C18 files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair C18 file corruption. You can restore the file from a backup or use Dassault Systèmes S.A. help.
The program indicates that the file is encrypted or corrupted. The encrypted C18 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 of the system directories are excluded from modification. The problem is only writing to the file, not reading it. Copying the C18 file to another location will fix the problem.
This problem only occurs with more complex files. 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 C18 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.
