Do you have the of this file, or are you trying to identify the source where it was downloaded?

In the context of file sharing or large downloads, "piece" often refers to one of several parts of a larger file. Here are the most likely scenarios for this specific file:

: When a large file (like a game, high-definition video, or software suite) is too big for a single upload, it is split into "pieces." You usually need all numbered parts (e.g., PQ12Fi.7z.001, PQ12Fi.7z.002) in the same folder to extract the contents.

: Look for files with the same name but different extensions (like .001 , .002 ) or similar random strings.

: If you are seeing this in a download folder, it may be a temporary segment created by a manager like JDownloader or a BitTorrent client. How to open it:
