A145fw.tar Instant

Wait, the user's query is a bit vague. They said "create an piece" with the tar file. Maybe they want to create a specific content within the tar or extract a piece of it. Without more context, it's hard to tell. But since they mentioned "create," maybe they want to generate a new tar file. Let me outline steps for both creating a new tar and adding to an existing one, in case that's what they need. Also, maybe they want to know how to extract specific parts of the existing tar.
