BNDL file is known as game data bundle file. The main purpose of this file is to store data files in an archive.
There are several games which use this file format to store various type of data in one single archive. Generally the file contains sound files associated with the game. As the sound files are small in size therefore the BNDL file is used to contain a number of sound files which are closely related with each other in the game. This file format is used only for archiving and no compression is done to reduce the file size.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .BNDL file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .BNDL file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .BNDL file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
