How to open DAT2 file?
An often recurring problem with XYplorer Thumbnail Cache is that DAT2 is not associated with the correct program file. Thus, when you open DAT2, 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 DAT2 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 XYplorer
An often overlooked issue is to make sure that XYplorer is installed on the computer. To do this, enter the name XYplorer into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support DAT2 files.
Programs to open DAT2 file
Remember to download programs supporting DAT2 files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of XYplorer with DAT2 files
However, it may happen that the application itself does not cause the DAT2 file to open in the XYplorer application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. 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. The "always use the selected program ..." field will set the XYplorer application as the default for handling the DAT2 file.
Step 3. Update XYplorer to the latest version
If, despite the association of the XYplorer program with the XYplorer Thumbnail Cache file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Donald Lessau page and install.
Step 4. Check for the following problems with the DAT2 file
Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:
The DAT2 file may be unusually small compared to the original file. This suggests truncating the DAT2 file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the DAT2 file that we want to open. Sometimes virus-infected DAT2 files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the DAT2 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 DAT2 file corruption. The easiest way to restore the file is from a backup or by contacting Donald Lessau, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted DAT2 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. The problem is only writing to the file, not reading it. Copying the DAT2 file to another location will fix the problem.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes you have to wait for the session to the file DAT2 to close. However, some background programs may block the DAT2 file while scanning. If nothing helps, please reset the device.
