Hi, I have couple questions for you... Be gentle, I'm a beginner

1. If I know a file's size in bytes, how can I convert it to decimal that shows it in megabytes with 3 or more digits? As in, 0,00 MB?

2. How can I count many files together in format like 0,00 MB?

3. If I know an mp3 file's lenght in seconds and milliseconds (stored in System.Time variable), how can I display it like 00:00:00 (hh:mm:ss)?

5. How can I count file lenghts together like using format 00:00:00?
