File Type of the Day
Advanced Audio Coding File
An AAC file is an audio file similar to an .MP3 file but compressed with Advanced Audio Coding (AAC), a lossy digital audio compression standard. The lossy compression maintains quality nearly indistinguishable from the original audio source, making it optimal for compressing music data.
VobSub Subtitles Index File
An IDX file is a subtitles index file created and used by VobSub, a program that allows users to extract subtitles from DVDs. It contains a list of plain text settings and timestamps used to show the subtitles that a .SUB (VobSub Subtitles) file contains.
