How can I keep the historical data in MT4

 

Dear all

I found my Metaeditor stopped running in these days and I want to reinstall MT4 in my computer but I don't know how to keep the historical data.

As you know, when you reinstall MT4, all daily data from the charts which was downloaded day by day before may not be resumed after you reinstall it again. Does anybody know which folder cantains those data so that I can cut it out to preserve those precioius data.

Thank for your kind help!
