AVI is a classic Microsoft video format from the 1990s. It offers broad compatibility and good quality but large, inefficient files, so it is mostly replaced by MP4 today - though it is still common in older archives.
AVI opens in Windows Media Player, VLC and most desktop players; for phones and browsers, converting to MP4 is the reliable choice.
FLAC is a lossless audio format that compresses music with zero quality loss - every detail of the original recording is preserved. It is the favourite of audiophiles and for archiving CDs, though files are much larger than MP3.
FLAC plays in VLC, foobar2000, and most modern players; for iPhones or car stereos that reject it, convert to MP3 or M4A.
