Then I presume when you CTRL+E any file in FTP client, it downloads the file in question, opens it with its associated software. And once file is saved and closed [fclose], client checks for the usage lock status [flock] : if no lock is in place, it uploads the edited version and deletes it from TEMP folder. Did I get it right?
If so, I guess this Feature request is unnecessary after all. You guys have done all the work, thanks...
