File Type 1Microsoft Word AutoSave File
What is an ASD file?
An ASD file is a temporary backup created by Microsoft Word, a word processing program used to author documents. It contains a snapshot copy of the currently opened Word document. ASD files are used for automatic backup and recovery of documents in Word in case of an unplanned disruption or program crash.
ASD files were introduced by Microsoft with the release of Word 95 (Word 7.0) in 1995 and are still used by current versions of Word. The application creates ASD files automatically even if the "Always create backup copy" option (this setting informs Word to generate .WBK files for documents) is disabled in Word.
Word saves ASD files in the following default directories:
Windows 8/8.1/10: [user]\AppData\Local\Microsoft\Office\UnsavedFiles
Windows Vista/7: [user]\AppData\Roaming\Microsoft\Word\
Windows XP: [user]\Application Data\Microsoft\Word\

Programs that open ASD files
File Type 2Ableton Live Sample Analysis File
.ASD File Association 2
File created by Ableton Live, an audio production application; created when a new sample is recorded or when a sample is imported for the first time; contains metadata about the audio sample that 1) enables the software to display waveform data, and 2) speeds up performance when stretching the sample to fit a particular meter.
Ableton Live creates ASD files in the same directory as the recorded or imported sound clip. The ASD filename is the sound clip filename with the ".asd" extension added. For example, if you import song.wav, the software creates song.wav.asd.
NOTE: If you do not want Ableton Live to create ASD files, turn off the "Create Analysis Files" option, which is located in the "File Folder" tab of the Preferences window.
