Programs to open DRU file

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

Step 2. Create association of EAGLE Layout Editor with DRU files

If the application is or has been freshly installed, but the DRU file still does not use the EAGLE Layout Editor program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Changes can be made using the "Change" button. 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 DRU file with the EAGLE Layout Editor program.

Step 3. Update EAGLE Layout Editor to the latest version

The fault may also lie with the EAGLE Layout Editor program, it is possible that EAGLE Design Rules requires a newer version of the program. This can be done using the application (if it provides such options) or from the CadSoft Computer, Inc. website and install the latest version.

Step 4. Check for the following problems with the DRU 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 DRU file may be unusually small compared to the original file. Usually this applies to DRU files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file DRU or the program directory. As a result of the scan, sometimes it is not possible to recover DRU files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the DRU file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular DRU file corruption. You can restore the file from a backup or use CadSoft Computer, Inc. help.
The program can also signal the fact of encryption. The encrypted DRU 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 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. If possible, you can try to move the DRU file to another location.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the DRU file while scanning. If nothing helps, please reset the device.
