Software Identification tags are stored on the computers on which the software is installed. The standard allows for operating system vendors to specify where software identification tags are located.If the platform provider doesn’t specify a location, software identification tags are stored in commonly known shared locations such as:
- <root>/Library/Application Support/
on Apple Macintosh OS X Leopard - Application Directory/ /contents on Apple Macintosh OS X versions earlier than Leopard
- usr/share/
on UNIX and Linux - %AllUsersProfile%Data<software creator regid> on Windows 2000, XP, and Server 2003
- %Program Data%<software creator regid> for Microsoft Vista and later and Microsoft Server 2008 and later
Software identification tag files have.swidtag file extensions for easy recognition.
