Convert all FLAC files in a folder to MP3s

The next script takes a folder path as imput, checks all the FLAC files in that folder, and creates MP3 files for each FLAC file found. There is only one prerequisite: FFMPEG should be installed. Save the script as "ConvertFlacToMp3.bat"

Usage:

C:\> ConvertFlacToMp3.bat {path to FLAC files}

or:

Create a shortcut to this script on the desktop and you can drag folders (from Windows Explorer) to the icon.

There are couple of tricks in the script:

- Normalization of the passed folder (e.g. removal of qoutes, required for drag-and-drop)

- Enumeration of FLAC files in the folder

- Filename contruct of the MP3 filename 

You play around with the script and find out yourself. One improvement could be that the MP3 files are stored in a (new) seperate folder.
