At the first start, Kaseto will ask for the directory where the music and audio books are stored. The selected directory will be scanned. All found audio files will be automatically processed on the basis of their tags to a clearly represented music collection. Neither the audio files nor the directory structure will be modified. Kaseto supports the audio formats FLAC, M4A (AAC), MP3, OGG and WMA.
The freeware detects new audio files as well as changed tags or covers when starting and updates the music collection automatically. Missing or incorrect tags (titles, artists, genres, CD numbers and track numbers) of songs and albums can be edited directly in Kaseto as well as it is possible to choose another another image as cover for an album.
