Is possible integrated diff tool like WinMerge ( http://winmerge.org/ ) ? Best using is shown by image - captured from PSPad. Right click on some tab means diff with actual tab... but some shortcut or something will be enough.

For anyone interested in doing this, here is how:

Create a new Menu item in Integration, then set it to shell and then add this command line:

"C:\Program Files\WinMerge\WinMerge.exe" @FName@ c:\dev\xampp\htdocs\mxdcsweb1\@RelFName@

make sure the paths are where your projects and programs are. @FName@ is the name of the file or folder from the current project. c:\dev\xampp\htdocs\mxdcsweb1\@RelFName@ must be your full path to the project that you wish to have compared with your current project.

Make sure you enable "Show this command in workspace popup" then enable the options: for files, for directories and projects.

Then it will let you run winmerge from within nusphere, and compare files or folders.
