How to open U3I file?

An often recurring problem with U3 Application Information Format is that U3I is not associated with the correct program file. Thus, when you open U3I, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the U3I 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 U3 Launcher

The first step is to check if the computer has the U3 Launcher program installed. The easiest method is to use the system search engine by entering the program name U3 Launcher in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below you will find a list of applications that support U3I files.

Programs to open U3I file

Remember to download programs supporting U3I files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of U3 Launcher with U3I files

However, it may happen that the application itself does not cause the U3I file to open in the U3 Launcher application, but you can set it manually. 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. Using the "Change" button we can set the program to handle this type. 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 U3 Launcher application as the default for handling the U3I file.

Step 3. Update U3 Launcher to the latest version

If, despite the association of the U3 Launcher program with the U3 Application Information Format file, the file still does not open, check the program version and possibly update it to the newest version.

Step 4. Check for the following problems with the U3I file

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. This suggests truncating the U3I file contents when downloading or copying. 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. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our U3I file. Sometimes virus-infected U3I files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the U3I file. 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.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular U3I file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted file U3I 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. The problem is only writing to the file, not reading it. If possible, you can try to move the U3I file to another location.
This problem only occurs with more complex files. In this case, the U3I file is blocked by the first application to open it. Running programs (including those in the background) should be verified. 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 nothing helps, please reset the device.
