How to open DTN file?
The main problem with TunnelCAD Import Or Export is that the DTN file is incorrectly associated with programs. This causes the file DTN 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 DTN 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 TunnelCAD
An often overlooked issue is to make sure that TunnelCAD is installed on the computer. This can be achieved by typing TunnelCAD into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file DTN with TunnelCAD. Later in this article you will find a list of programs that can open DTN files.
Programs to open DTN file
Remember to download programs supporting DTN files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of TunnelCAD with DTN files
However, it may happen that the application itself does not cause the DTN file to open in the TunnelCAD application, but you can set it manually. 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. Using the "Change" button we can set the program to handle this type. 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 DTN file with the TunnelCAD application.
Step 3. Update TunnelCAD to the latest version
The fault may also lie with the TunnelCAD program, it is possible that TunnelCAD Import Or Export requires a newer version of the program. This can be done using the application (if it provides such options) or from the IQSoft website and install the latest version.
Step 4. Check for the following problems with the DTN file
If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:
The affected file may be 0 KB or smaller than expected. This suggests truncating the DTN file contents when downloading or copying. Downloading the file again should fix the problem.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the DTN file that we want to open. However, remember that not every infected DTN file can be recovered, so it is important to take care of regular backups.
Older version of DTN file may not always be supported by the latest software version. 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. Sometimes the program itself has options to repair the most popular DTN file corruption. You can restore the file from a backup or use IQSoft help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted DTN files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. Copying the DTN file to another location will fix the problem.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the DTN file again. However, some background programs may block the DTN file while scanning. If nothing helps, please reset the device.
