[eluser]7amza[/eluser]
hey,
im working in a project ..the project structures is :

/system
app/application1
app/application2
app/application3
index.php
application2.php
application3.php
..
so all is fine , the only problem is that all applications share the same libraries and core extending files (im using CI2.0) and libraries extending files and the config folder and models .
so there is anyway to make all these files shared ?
please any workaround solution will be also fine because there is a month ago im searching for a solution .
sorry for my poor english

Just an idea, not tested, under CI 2 You should be able to set package paths which point to Your common stuff.
