## Creating an MBM File

Symbian OS programs typically store bitmaps for application icons or other purposes in the Symbian OS multi-bitmap (MBM) file format, as described in MBM File. The Edit MBM/MIF Contents or Edit MBM Contents window allows you to create an MBM file.

#### To create an MBM file

1. In the Symbian Project Navigator view double-click a .mmp file (Figure 1) to open the MMP Editor (Figure 2).

You can now use the MBM Editor to add bitmaps, with and without masks, to the MBM file.

4. Enter a name for the mbm file in the Target file text box.
5. Add bitmap files to the editor by using the Add From Project or Add From Filesystem buttons.

Additional information for the MBM editor fields is provided in MBM Editor.
