This seems like a big thing to ask for, but when WinSCP has multiple users editing the same file it overwrites changes one user makes with the changes a different user makes. Basically whoever saves the file last is whose changes take effect. This seems to be because WinSCP overwrites the file on the server with the remote file whenever a change is made (the way an FTP traditionally operates). Is there any way around this? Is there a way to make an FTP save the changes to a file only. I don't quite understand how synchronous file editing works, maybe the file has to be being edited on the server and not on the remote computers for this to work. Maybe the append option will allow the file editing to behave as if it were synchronous file editing by appending the changes to the file with every save by the individual remote users? What do you think?
