This naming convention (e.g., [RandomCharacters].part[Number].rar ) is common for multi-part archives of movies, software, or games.
If the parts are unusually small (a few KBs) or all identical in size, they are likely suspicious.
Return to the forum post, thread, or index where you found the link; the description is usually listed there.
Before attempting to extract it, run the file through a service like VirusTotal to check for malicious signatures. E7GH7Y9UYC.part3.rar

Do you have the or the original name of the software or media this file is supposed to represent?
