Creating patches

Using GNU Diff: 1. Download and install GNU Diff .; 2. Type cmd in Run and tab your way to where GNU Diff is installed.; 3. Write diff -[parameter(s)] <path to the untouched file or folder> <path to the changed file or folder> > my-diff.diff; 4. A file, my-diff.diff will now be created in the directory which GNU Diff is placed. Other formats of files (such as .txt) can of course be created.; Example: C:\Program Files\GNU Diff>diff -uNr dcplusplus_orig dcplusplus_chan > my-diff.diff
C:\Program Files\GNU Diff is where GNU Diff is installed.
The parameter u means the diff will be unified. N means that GNU Diff will show output even if a file doesn't exist in one of the two folders. r means that GNU Diff will go through subdirectories and give output on which directory and file differ.
dcplusplus_orig is the folder that is untouched and what the changes is going to differ against.
dcplusplus_chan is the folder where changes has occured.
The actual diff is my-diff.diff.
Parameters and more information how-to use GNU Diff can be found in the documentation for GNU Diff which should have been accommodated with GNU Diff. Otherwise, click here
