File Associations
  

By using File Associations, you could view a file with a external program and edit it via another external program.

View File - Sets program to view files on FTP server

FileMask(*.*): defines masks for files to be viewed by the "Open with" program
Open with: Tell FTPRush uses what program to open file


Edit File - Sets program to edit files on FTP server

FileMask(*.*): defines masks for files to be opened by the "Open with" program
Open with: Tell FTPRush uses what program to edit file

Tips:
you can use semicolons(;) to separate filemasks for same item, for example: *.chm;*.jpg;*.doc, so you could open these files by using one external program
