The first thing you should do is just "doubleclick" on the DLT 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 Free DELTA

Step 2. Create association of Free DELTA with DLT files

If the application is or has been freshly installed, but the DLT file still does not use the Free DELTA program, it means no 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. Changes can be made using the "Change" button. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the DLT file with the Free DELTA application.

Step 3. Update Free DELTA to the latest version

If, despite the association of the Free DELTA program with the VCTEditor 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 SourceForge.net website or update the program from the application.

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

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the DLT file. The only repair option is to download the file again.
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. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file DLT or the program directory. Sometimes virus-infected DLT files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the DLT file. These problems are known and are often very easy to fix using the software developers's website.
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 DLT files. You can restore the file from a backup or use help.
The program can also signal the fact of encryption. The encrypted file DLT except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
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. If possible, you can try to move the DLT file to another location.
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. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the DLT file again. Some anti-virus or backup software may occupy the DLT file for a certain period of time. If nothing helps, please reset the device.
