.FLAC File
What is it?
FLAC (Free Lossless Audio Codec) compresses audio without losing any quality, unlike MP3 — popular with audiophiles who want CD-quality sound at a smaller size than uncompressed WAV.
How do I open it?
Plays in VLC, foobar2000, and most modern media players; some older devices only support MP3 and need a conversion first.
Is it safe?
Yes, FLAC only contains audio data.
Can I delete it?
Safe to delete once no longer needed; convert to MP3 first if you need a smaller copy for a device with limited storage.
