• How can I convert all .webm files in a folder to .m4a or .mp3 ? [duplicate]

  8 mai 2021, par NimishP

  I have a folder filled with .webm and .m4a files.

  


  Is there a way, using either Windows Command Prompt or a Python script, to convert all of the .webm files to .m4a OR to convert all .webm files AND .m4a files to .mp3 files ?

  


  I've tried using FFmpeg, but that only works for single files.

  


  How would I use this to mass convert all of the .webm files to .m4a files in a given folder/directory, if possible ?
If not, is there another library I can use to do this ?

  Renames x86_64 specific asm files

  Renames all x86_64 specific assembly files to consistently
  end in _x86_64.asm. This will be useful for build systems to
  handle these files differently.
  All new 64-bit specific assembly files should use the new
  naming convention.
