I am able to run 6 instances of the Compare-it with out too much problem,
However the biggest problem is when I compare the same file to two others and in both I make a change to the template. Opps, when I reload the changed file when I go back to the same file changed in another instance.
I really like that the file is reloaded if changed outside. However, this is a problem when the file has been locally changed but not saved too.
The real solution of course is difficult unless all 3 files are under the control of a single instance of the program. Or perhaps some logic like the suggestions below can make multi-file compare reasonable until 3+ file compare is ready.
1. May I suggest that when a file has been changed, and Compare-it is minimized, then the ICON in the task bar/toolbar could flash or change colour to warn that the file needs to be discarded or saved?
2. May I suggest that when a file has been locally changed and the file has been changed externally, before I reload it, WARN ME so I can rename and save the local file first.
3. perhaps you can look into opening an new instance of Compare-it to show the differences between the local changes and the external changes.
, I can only see one problem - you can miss a difference when same block A is found in files 1 and 2, and similar block B found in files 1 and 3. When blocks A and B only differs with additional line, it can be difficult to see it. Still, your method is quite good. I can also recommend trying
