So follow these steps and You will be able to switch Your Data.pak files fast (If u are using hacks of course)
1. Make copy of Your normal Data.pak
2. Edit it with any hacks u want
3. Rename it as Data1.pak
4. Cut+Paste it in Your data folder where is normal Data.pak
5. Launch logintool
6. Connect to the server and when client starts just close it but don't close logintool
7. Go in Your data folder and rename Data.pak as Data2.pak and rename Your edited Data1.pak as Data.pak
8. Connect to the server and You should be able to play with Your hacks
I think this is much faster way to switch Your Data.pak than copying it each time from other folder.
Hope I helped someone...
