- Description
- The OTB (Nokia Over The Air Bitmap Image) file format is a type of image file developed for use on Nokia mobile devices. These files are specifically optimized for efficient transmission and display on Nokia phones, particularly older models. The OTB format is designed to be compact to facilitate over-the-air (OTA) transmission, which was an essential feature in the era of limited bandwidth and data transfer capabilities. The format supports monochrome graphics, making it suitable for simple images like icons and logos.
- An EMZ file contains an Enhanced Metafile (.EMF file) that has been compressed with the .GZIP compression algorithm. It is compressed to reduce storage space and be more easily transferred between applications. EMZ files are typically used by Microsoft programs such as Visio and the Office suite, which includes Word and PowerPoint.
