In Postman, select Import > Migrate to Postman > Other API Clients.
Select files or folder, then select the files or folder you want to import. You can select individual exported collection and environment files, or you can select the rangav.vscode-thunder-client folder:
Select Open. Postman checks if the selected files are valid Thunder Client files.
If the files are valid, you can select Start Migration. A window appears showing the migration’s progress. When the migration is complete, select Dismiss.
