.spb File Extension

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

what is a .spb file?

The SPB file extension is affixed to saved Flight Simulator Mission Files, and this file format was developed by Microsoft. Generally categorized as game files, these .spb files are implemented by Microsoft ESP, which is a toolkit for applications that are used to simulate real life situations. The toolkit stores flight simulator mission conditions, which also includes the mission state "triggers" and "actions". The state is then saved in an FLT file, considering its specific part in the entire saved game. ESP technology is only for games like Microsoft Flight Simulator X. The purpose of SPB files basically originates with the creation of Microsoft ESP in XML formats, and these are saved in binary SPB formats. If users intend to convert X SPB files to XML, a program called spb2xml can be used.

how to open a .spb file?

Launch a .spb 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 .spb file will open it.

In this case, when you try to open a .spb file, you can tell Windows which application is the correct one for that file. From then on, opening a  .spb file will open the correct application.

Spb2xml is a utility used in converting SPB files or SimProp Binary files to XML. It decompiles SimProp Binary files and produces a source for XML that can be read and reformed. SPB file is a format integrated in Microsoft Flight Simulator X; it stores various data that can be compiled using different XML files. XML or Extensible Markup Language on the other hand is a string of characters made up of legal Unicode characters. The markup is analyzed by the processor then transfers the structured data into an application. SPB files are assembled with the help of simpropcompiler.exe and this tool can reverse that task. Spb2xml decompiles the SPB file and extracts the original XML document. Users have to be conversant in entering command lines and familiar in DOS style command line formats to make this utility to work.

a word of warning

Be careful not to rename the extension on .spb 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.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .spb. 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.
