=Diff files=
A diff file is a file to make:
*implementation of a modification easier
*check what and where you modified things
*share your modifications with the rest of the world
*it is also an easy way for people that give support on forums to check themselves what is wrong to the modifications you made

==Creating .diff files using the tortoise menu==
#right click on the folder
#goto TortoiseSVN menu
#click create patch
#save as .diff file

==Manually Creating .diff files (knowing the mechanics and repairing .diffs if needed)==
#create a new txt file
#rename the .txt extention to .diff
#start with pointing out the index (path where the diff files will patch)
#*example:[code]Index: src[/code]
#add a ========================================= line to indicate the next file
#*example:[code]=========================================[/code]
#add the patch of the file where content will be removed (---) and add the revision
#*example:[code]--- src/common/mmo.c (revision 12300 Stable)[/code]
#add the path of the file where content will be added (+++) and add (working copy)
#*example:[code]+++ src/common/mmo.c (working copy)[/code]
#add the location of the lines that need to be modified in this way:
##@@
##-100: start reading original lines at line 100
##,5: read 5 original lines
##+100: start reading new lines at line 100
##,7: read 7 new lines

#add a "-" and write the line that must be modified

==Using .diff/.patch files to patch your server==
'''Windows''':
#go place the folder in the index folder
#richt click the *.diff file and go to TortoiseSVN menu
#click patch

'''Linux''':
cd /path/to/your/server/folder
patch -p0 < /path/to/patch/file/filename.extension
