Force opening file with SourceTree TextEditor

[fredvol P]

Hello, I have a internal software  producing file with  extension  (*.par)  , but inside it is a XML file.

SourceTree do not shows me the difference between commit.

Can I force sourcetree to  consider *.par like *.xml ? without changing the windows file extension association.

I still want  the file .par to be open with  my internal software when  i double click on it.
I managed to make a "custom action" to open it with Notepad++, but it does not shows ma the difference with the previous commit.

Thanks in advance.

SourceTree does not decide whether to diff or not, it relies on Git to determine that. There are some solutions and specific causes for what you are seeing here: http://stackoverflow.com/questions/6855712/why-does-git-treat-this-text-file-as-a-binary-file
