How to open DR4 file?
The main problem with AllyCAD Drawing is that the DR4 file is incorrectly associated with programs. This is manifested by the fact that DR4 files open in unusual applications or do not have an assigned program. How to solve such a problem?
The first thing you should do is just "doubleclick" on the DR4 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 AllyCAD
In this case, you should first verify that the AllyCAD application is installed on the computer. The easiest method is to use the system search engine by entering the program name AllyCAD in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open DR4 files.
Programs to open DR4 file
Remember to download programs supporting DR4 files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of AllyCAD with DR4 files
However, it may happen that the application itself does not cause the DR4 file to open in the AllyCAD application, but you can set it manually. 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 set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the AllyCAD application as the default for handling the DR4 file.
Step 3. Update AllyCAD to the latest version
If, despite the association of the AllyCAD program with the AllyCAD Drawing file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Knowledge Base Software website or update the program from the application.
Step 4. Check for the following problems with the DR4 file
The problem may also be with the file itself if the above steps don't work. The most common file problems are:
The affected file may be 0 KB or smaller than expected. This suggests truncating the DR4 file contents when downloading or copying. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the DR4 file that we want to open. However, remember that not every infected DR4 file can be recovered, so it is important to take care of regular backups.
Older version of DR4 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.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged DR4 files. The easiest way is to restore the file from a backup, if there is one, or contact Knowledge Base Software
The program indicates that the file is encrypted or corrupted. The encrypted DR4 files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. Copying the DR4 file to another location will fix the problem.
This problem usually affects 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. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the DR4 file for a certain period of time. If nothing helps, please reset the device.
