How to open CTT file?
The most common problem when using Messenger Contact List is that a specific CTT is not associated with the program. This causes the file CTT 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 CTT 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 Microsoft Messenger
An often overlooked issue is to make sure that Microsoft Messenger is installed on the computer. To do this, enter the name Microsoft Messenger 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 CTT with Microsoft Messenger. Later in this article you will find a list of programs that can open CTT files.
Programs to open CTT file
Remember to download programs supporting CTT files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Microsoft Messenger with CTT files
If the application is or has been freshly installed, but the CTT file still does not use the Microsoft Messenger program, it means no association. It is most convenient to call the context menu with the right mouse button and select 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the CTT file with the Microsoft Messenger application.
Step 3. Update Microsoft Messenger to the latest version
If, despite the association of the Microsoft Messenger program with the Messenger Contact List file, the file still does not open, check the program version and possibly update it to the newest version.
Step 4. Check for the following problems with the CTT 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 CTT file may be unusually small compared to the original file. This suggests truncating the CTT 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. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the CTT file that we want to open. As a result of the scan, sometimes it is not possible to recover CTT files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of CTT file may not always be supported by the latest software version. 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. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged CTT files.
The program can also signal the fact of encryption. The encrypted CTT 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. It is best to move CTT to a different directory.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the CTT file for a certain period of time. If the problem persists, restart the machine.
