• "Droplet" batch script - filenames containing ampersands

  16 août 2014, par stephenwade

  I’m trying to create a batch file that can have other files dropped onto it. Specifically, I’m using ffmpeg to edit audio files produced by a handheld voice recorder. The problem is when using filenames with ampersands (&). Even when quoting the input, anything after the & is dropped off, but only when files are dropped onto it ; if the filename input is typed on the command line, the script works fine. Before the cmd window closes, I briefly see the rest of the filename with an error saying it is not recognized as a valid command.

  Here’s my script :

  rem Change to drive and directory of input file
  % d1
  cd % p1
  rem ffmpeg : mix to one channel, double the volume
  
  %HOMEDRIVE%%HOMEPATH%\ffmpeg.exe -i "% nx1" -ac 1 -vol 1024 "% n1 fixed% x1"
  pause
  

  Here’s what appears on the command line, after dropping "ch17&18.mp3" :

  C :\Users\computergeeksjw\Desktop>C :\Users\computergeeksjw\ffmpeg.exe -i "ch17" -ac 1 -vol 1024 "ch17 fixed"
  [...]
  ch17 : No such file or directory
  

  In case it matters : I’m using the Windows 8 Developer Preview. Is this causing my problem ? Does the same error occur on Windows 7 or earlier ?
