About SD files
The .SD file extension is heavily fragmented. Primarily, it functions as an ArcGIS Service Definition file or an ArcGIS Scene Document created by Esri ArcGIS. Alternatively, it is widely used as a game save file for Nintendo DS or Sega Dreamcast, a scientific UV-Vis spectral data file for Agilent ChemStation, or a Microsoft Train Simulator shape definition. You can open GIS versions with ArcGIS Pro. UV-Vis files require proprietary lab software from Shimadzu or Agilent. Game saves require specific console emulators. Users face severe compatibility issues because this extension is shared across dozens of unrelated platforms. A scientific lab file will fail to open in GIS software. Most .SD formats are proprietary, locked behind expensive legacy subscriptions, or unreadable by standard text editors and web browsers. For ArcGIS .SD files - which are actually internal 7Z archives - extracting the contents to ZIP or individual files is the most practical conversion target. Train Simulator files are UTF-16 encoded and convert easily to TXT. This file format is notoriously difficult to open or convert due to the lack of a unified standard. Often, only the original creator software can properly parse the underlying binary data.
Convert.Guru analyzes your SD file, detects the exact format, and lets you read the text inside.
If you want to convert SD file to HD, SE, MYR, RM, SEM, MP3, WAV, AAC, FLAC, OGG, WMA or M4A, you can use ArcGIS Pro or similar software from the "ArcGIS Service Definition" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to SD, try ArcGIS Pro or another comparable tool in the "ArcGIS Service Definition" category.
The SD Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SD converter.
