How to open TNA file?

The main problem with Topocad Net Adjustment is that the TNA file is incorrectly associated with programs. This causes the file TNA to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

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

The first step is to check if the computer has the Topocad program installed. To do this, enter the name Topocad into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file TNA with Topocad. Below you will find a list of applications that support TNA files.

Programs to open TNA file

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

Step 2. Create association of Topocad with TNA files

However, it may happen that the application itself does not cause the TNA file to open in the Topocad 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 select the desired program. 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 Topocad application as the default for handling the TNA file.

Step 3. Update Topocad to the latest version

If, despite the association of the Topocad program with the Topocad Net Adjustment file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Adtollo website or update the program from the application.

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

Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:

The TNA file may be unusually small compared to the original file. This suggests truncating the TNA file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the TNA file that we want to open. Sometimes virus-infected TNA files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the TNA files changes over time. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged TNA files. The easiest way is to restore the file from a backup, if there is one, or contact Adtollo
When reading, a message appears that the file was encrypted or corrupted. The encrypted TNA 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. The problem is only writing to the file, not reading it. It is best to move TNA to a different directory.
This can happen on a file that does not support multiple access. 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 TNA file again. However, some background programs may block the TNA file while scanning. If nothing helps, please reset the device.
