Moving files manually between different computers can be a daunting task. But Microsoft tried to solve this problem by introducing the Migration tools, Windows Easy Transfer Tool (WET) for home users, and User State Migration Tool (USMT) for IT professionals.

Hamid Imtiaz, Chief Technology Officer at Remo Software, says these tools are designed to help Windows users backup and migrate data like files, folders, documents, profiles, user files, user accounts, desktop files, application settings, start menu settings, Internet Explorer settings, as well as Favorite bookmarks, to a different computer or laptop running on the same OS version or a different version of Windows OS, using a transfer cable, or storage devices, or over LAN.

All of the files and data that you want to move will get compressed and stored in a package called a provisional package.

Windows Easy Transfer tool (WET) creates a compressed copy of the user’s files and settings in a single WET file to move the data to another computer running on the same version of Windows OS.

The User State Migration Tool (USMT) creates a compressed copy of the user’s data and settings in the MIG files to move the user data to another system running on another Windows OS version.

Reasons Behind the Loss of .mig and wet Files from Windows System 

  • Accidental Deletion: You might have accidentally deleted the MIG files from the intermediate store or used a data cleanup utility to delete some of your old files.
  • Formatting the Drive Where You Have Saved the Migration Files: Formatting the storage devices where you have saved the MIG or WET files by taking backups also leads to permanent loss of .mig files.
  • Virus Attack or Malware Infection: Connecting the drive where your MIG files are stored to a public or virus-infected system can also corrupt or delete your files.
  • Hardware Failure: A hard Drive or any other storage device, such as a USB Flash Drive where you have stored the compressed copies of your user data, might fail or get physically damaged, making you unable to access the saved files.
  • Operating system Crash: If your MIG files were being created, modified, or moved and suddenly the Operating system crashed, or your system got unexpectedly shut down due to power cuts, etc. Then, you might also lose your Migration files.

Now that you know the reasons, let’s go through some valuable tips to ensure you never lose Windows migration files and other vital data in the future. 

Tips To Prevent Loss of .mig Files in the Future

  • Regularly backup your MIG files and all other important files, folders, and other data. This will help you restore them in case of data loss.
  • Since we have just talked about backing up MIG files, also ensure that the files are saved in other external locations such as any other Hard Drive, Solid State Drive, or USB.
  • You saved a backup copy of the MIG files on the Cloud. This will give you access to your MIG files from any computer, laptop, or device.
  • Be extremely careful when you are using file cleanup tools. 
  • Always use a reliable Antivirus tool regularly to ensure your system and external storage devices are clean and free from any unwanted viruses and malware.
  • Always use reliable data recovery utilities like Remo in case of data loss. Using an unreliable tool might do more harm than good.
