Renaming them is SOOOO easy! In Windows Explorer, just click once on the filename, then click the filename again (do not double-click). This will highlight the name and leave you with a flashing cursor at the end of the filename. Using the left & right arrow keys to move the cursor, and use BACKSPACE to delete a character to the left of the cursor or "DELETE" to delete characters to the right of the cursor, you can change the name however you like. When you're through, either press ENTER or click outside of the filename (anywhere but the actual name), to save the new name.

You're right about the RAR files needing to be named with sequential extensions. They need to be named with the same base filename (the name to the left of the extension) and each file needs its own respective sequential extension: (.rar, .r00, .r01, .r02, .r03) or (.001, .002, .003, .004)

Once you have them renamed correctly, you will **ONLY** extract the files from the very first file. WinRAR will automatically see all of the other files (sequentially extensioned) as being part of the same file and will continue through them all until the data is fully extracted. The problem you're running into is you're trying to extract a file from the second segment but the start of the file you're extracting is actually in the first segment.
