Hi everybody,
 

 we need to set the content-description element within the file haeder of every attached file individually.
 Therefore we looked for some option to achieve this but we couldn't find anything.
 

 Currently we searched the description and options of  blat v3.2.15 (windows).
 

 We have to use windows, linux is NOT an option in our scenario (sorry).
 

 Any ideas?
 

 I also tried to compile blat with cygwin and gcc 5.4.0 but I got lots of errors.
 I'm not a cpp expert...
