How to open CU1 file?
An often recurring problem with Photoline 4 Curve is that CU1 is not associated with the correct program file. Thus, when you open CU1, the program selection wizard or some other program starts. How to solve such a problem?
The first thing you should do is just "doubleclick" on the CU1 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 Photoline
The first step is to check if the computer has the Photoline program installed. The easiest method is to use the system search engine by entering the program name Photoline 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 CU1 files.
Programs to open CU1 file
Remember to download programs supporting CU1 files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Photoline with CU1 files
However, it may happen that the application itself does not cause the CU1 file to open in the Photoline application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. 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. Checking the "Always use the selected program ..." box will permanently associate the CU1 file with the Photoline program.
Step 3. Update Photoline to the latest version
If, despite the association of the Photoline program with the Photoline 4 Curve 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 Impressum website and install the latest version.
Step 4. Check for the following problems with the CU1 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 CU1 file may be unusually small compared to the original file. This is most often caused by a problem while downloading the CU1 file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our CU1 file. As a result of the scan, sometimes it is not possible to recover CU1 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of CU1 file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged CU1 files. The easiest way is to restore the file from a backup, if there is one, or contact Impressum
The program indicates that the file is encrypted or corrupted. The encrypted CU1 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 of the system directories are excluded from modification. The problem is only writing to the file, not reading it. It is best to move CU1 to a different directory.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file CU1 to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
