What is TUB file?

The file with the extension TUB is the Raster Image Files file type. The creator of this file is Corel. Additionally, the Raster Image Files category contains 522 of other files. Paint Shop Pro Picture Tube is supported by 3 operating systems. The file will work on Linux, Mac OS, Windows systems, unfortunately not on others. It is recommended to use GIMP to handle this file. This is a program created by The GIMP Team. Alternatively, you can use 4 other programs. You can use PaintShop Pro, XnView in case GIMP cannot be used.

How to open TUB file?

The main problem with Paint Shop Pro Picture Tube is that the TUB file is incorrectly associated with programs. This is manifested by the fact that TUB files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the TUB 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 GIMP

The first step is to check if the computer has the GIMP program installed. This can be achieved by typing GIMP into the operating system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file TUB with GIMP. Later in this article you will find a list of programs that can open TUB files.

Programs to open TUB file

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

Step 2. Create association of GIMP with TUB files

If, despite the installed application, the TUB file does not start in the GIMP application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. 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 GIMP application as the default for handling the TUB file.

Step 3. Update GIMP to the latest version

If, despite the association of the GIMP program with the Paint Shop Pro Picture Tube 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 The GIMP Team page and install.

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

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

The TUB file may be unusually small compared to the original file. This suggests truncating the TUB file contents when downloading or copying. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the TUB file that we want to open. As a result of the scan, sometimes it is not possible to recover TUB files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of TUB 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 the failure. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular TUB file corruption. The easiest way to restore the file is from a backup or by contacting Corel, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted TUB files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
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 TUB file to another location.
This problem usually affects 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. However, some background programs may block the TUB file while scanning. If this does not work either, restart the device.
