What is WTML file?

The file in the WTML format belongs to the Misc Files category. Misc Files consists of 6033 similar files. WorldWide Telescope Data Format appears on 1 operating systems as a functional file. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. It is recommended to use WorldWide Telescope to handle this file. This is a program created by Microsoft Corporation.

How to open WTML file?

The most common problem when using WorldWide Telescope Data Format is that a specific WTML is not associated with the program. This causes the file WTML to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the WTML 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 WorldWide Telescope

The first step is to check if the computer has the WorldWide Telescope program installed. The easiest method is to use the system search engine by entering the program name WorldWide Telescope 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 WTML files.

Programs to open WTML file

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

Step 2. Create association of WorldWide Telescope with WTML files

If, despite the installed application, the WTML file does not start in the WorldWide Telescope application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the WTML file with the WorldWide Telescope program.

Step 3. Update WorldWide Telescope to the latest version

If, despite the association of the WorldWide Telescope program with the WorldWide Telescope Data Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Microsoft Corporation website or update the program from the application.

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

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

Very often, the file may be size 0 or incomplete. This suggests truncating the WTML file contents when downloading or copying. 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. If this is not possible, you can use the online scanner. However, it is important to scan the entire system, not only the file WTML or the program directory. Sometimes virus-infected WTML files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the WTML file. 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 this. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged WTML files. 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 WTML 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 WTML file to another location will fix the problem.
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. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the WTML file again. Some anti-virus or backup software may occupy the WTML file for a certain period of time. If this does not work either, restart the device.
