You're here because you have a file that has a file extension ending in .btif. Files with the file extension .btif can only be launched by certain applications. It's possible that .btif files are data files rather than documents or media, which means they're not meant to be viewed at all.

Files appended with the BTIF extension refer to data files with image data. These are called NationsBank check image files and can be viewed in a standard Web browser developed with support for Microsoft Windows-based systems. Users can install the NationsBank Check Viewing plugin application to implement support for these BTIF files, because this Web browser add-on application is required to view the content of a BTIF file. The data stored in a BTIF file may include text content encoded in ASCII, and these pieces of data can be the date the clearance and issuance dates of the check along with other details. These BTIF files also contain image data that may be compressed using a number of image file compression technologies, one of which is the JPEG file compression format. Bank of America, formerly known as NationsBank, in which the change of name happened in 1998, developed the BTIF format and the NationsBank Check Viewing plugin software. Mac users need to access a computer running on Microsoft Windows because the BTIF file is not supported by Web browsers developed for Mac platforms.

Launch a .btif file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .btif file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .btif files aren't yet associated with it. In this case, when you try to open a .btif file, you can tell Windows which application is the correct one for that file. From then on, opening a  .btif file will open the correct application.

Be careful not to rename the extension on .btif files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

A file extension is the set of three or four characters at the end of a filename; in this case, .btif. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
