About .flac files and .cue files

Hello guys,
Thanks for the help of everyone of you. Here’s one more question, again about .flac files. The other day I downloaded a few songs, but I got them as a single file. I mean, the songs are not separate. You can play them using VLC Player or something, but the songs have to be chosen using the slider. How can I separate the tracks from this one file?
One more question: How can I use .cue files? (But there are no .cue files in the above case.)
Thanks and regards

I don’t have any .flac files but I would try Audacity.

Import the CUE file in a burning app to burn the tracks to an audio CD…
