SDT - Siemens Desktop Theme File

What is a SDT file

SDT files are most commonly, but not exclusively, associated with Siemens mobile phones. They are used to store the desktop theme of such a mobile device, using a ZIP (compressed) format. The SDT file contains all needed information for the display of the desktop theme. This includes graphics (usually saved in the GIF format), sounds (usually saved in either the AV or MID format), and the layout. Since the file is, in its base, just a ZIP file, it can easily be decompressed by any ZIP-decompression program.

Other uses of the SDT file include gaming files (for sounds used by Electronic Arts games or Grand Theft Auto 3) and templates used in the page layout program SmartDraw.

Here's a small, but not exhaustive list of programs that can open SDT documents:

  • 7-Zip (Windows)
  • Corel WinZip (Windows)
