Hi, We have a product which produces audio files with extension .vsb files. Most of these files are getting downloaded from web for listening purpose. For listening we have a separate Application, which is used after the audio .vsb file is downloaded. .vsb is an encrypted audio file along with certain metadata for it. Some files having names with _, -, or space gets downloaded but the filename is truncated to the length of first occurrence of above mentioned characters. Files downloaded are of expected duration and size can but not able to play since filenames got truncated. This issue has become very critical now since we are facing the same issues
