Many fans still prefer collecting the original CDs and vinyl records for the complete artwork and "warm" sound.
A file is a compressed archive. It is used to bundle multiple songs, album artwork, or even entire discographies into a single, smaller file for easier sharing. Understanding RAR Files
If you extract the archive and see files ending in .exe , .msi , or .bat , delete them immediately. Music files should be in formats like .mp3 , .flac , or .wav .
Use an updated antivirus tool to scan the .rar file before you open it.
