     11Not a bug, but feature request.

     13I am using VFS (extfs). I have written program (backup extractor)  
     14which handle "copyout" and "list" commands from mc. But if I want to 
     15 copyout a whole directory (or a lot of files from archive), it is  
     16called FOR EACH extracted file. In my case, extractor (duplicity  
     17backupper, http://www.nongnu.org/duplicity/ ) starts very long time. 
     18 But it can extract whole directory quickly. 
     19 
     20I think if mc would pass to extfs script environment variable  
     21containing names of ALL the selected files (AND DIRECTORIES) on the  
     22panel before extracting, it would get ability to optimize extract  
     23script. For example, I can fully extract all needed files in  
     24temporary directory by ONE call to duplicity, and then just copy  
     25these files from temp directory to pathes needed by mc.
