What is a MIG file?
A .MIG file is primarily a Windows Migration Backup File created by Microsoft software. The Windows Easy Transfer utility and the command-line User State Migration Tool (USMT) use this format to bundle user settings, personal documents, and application data into a single archive. People use these backups to move data safely from an old computer to a new computer.
Because developers can reuse file extensions, a .MIG file can also be something else. Sometimes, WhatsApp Messenger or a Samsung device saves standard .JPG images with a .MIG extension. In rare cases, it might be a game save file or scientific data created by WaveMetrics Igor Pro.
How to open MIG files?
To restore a standard Windows Migration Backup File, you traditionally use Windows Easy Transfer. Because modern versions of Windows do not include this tool, you might need to use USMT or third-party extraction tools like MigRecover to get your files out. If your file is actually a renamed mobile image, simply renaming the file extension from .MIG to .JPG will let you view it in any standard photo viewer.
