Tips to open DU1 file
Can't open the DU1 file? You are not the only one. Thousands of users face similar problems every day. Below you will find tips on how to open DU1 files as well as a list of programs that support DU1 files.
DU1 file extension
The DU1 file is supported on 1 operating systems. Depending on your operating system, you may need different software to handle the DU1 files. Below is a summary of the number of programs that support and open the DU1 file on each system platform.
What is DU1 file?
The file with the extension DU1 is the Raster Image Files file type. Additionally, the Raster Image Files category contains 522 of other files. Atari ST Picture Image Format is supported by 1 operating systems. These systems consist of Windows, although it may occasionally be found on another system, it will be non-functional. The RECOIL application is recommended to open the file. It was released by Piotr Fusik and Adrian Matoga.
How to open DU1 file?
The main problem with Atari ST Picture Image Format is that the DU1 file is incorrectly associated with programs. This is manifested by the fact that DU1 files open in unusual applications or do not have an assigned program. This problem can be easily remedied.
The first thing you should do is just "doubleclick" on the DU1 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 RECOIL
The first step is to check if the computer has the RECOIL program installed. To do this, enter the name RECOIL 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 DU1 with RECOIL. Below you will find a list of applications that support DU1 files.
Programs to open DU1 file
Remember to download programs supporting DU1 files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of RECOIL with DU1 files
If the application is or has been freshly installed, but the DU1 file still does not use the RECOIL 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. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the RECOIL application as the default for handling the DU1 file.
Step 3. Update RECOIL to the latest version
If, despite the association of the RECOIL program with the Atari ST Picture Image Format file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the Piotr Fusik and Adrian Matoga website and install the latest version.
Step 4. Check for the following problems with the DU1 file
Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:
The affected file may be 0 KB or smaller than expected. Usually this applies to DU1 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. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the DU1 file that we want to open. As a result of the scan, sometimes it is not possible to recover DU1 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the DU1 files changes over time. 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. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair DU1 file corruption. You can restore the file from a backup or use help.
The program can also signal the fact of encryption. The encrypted file DU1 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 operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. 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 DU1 file to another location.
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. Closing other programs should help. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
