Help with an extraction error or a missing "part4"?
Based on the naming convention, this is the of a multi-volume RAR archive. You generally cannot open or view the contents of this file individually; you must have all parts (part1, part2, etc.) in the same folder and use a program like WinRAR or 7-Zip to extract the full file.
To help you with this, I need a little more context on what you mean by a "proper text."Information on what the video content actually is (e.g., a specific show, movie, or event).
A hash (like MD5 or SHA-1) to ensure the file isn't corrupted.
