Since someone was asking about search&replace tool I thought about another useful tool that comes in handy when one needs to work with lots of files without jumping from one directory to another.
You can use 2 windows explorer windows for that task and change windows sizes so they fit the screen, but... you can also use 2xExplorer program which is 2 windows explorers in 1 program. it helped me out numerous times.
