Hello Laz, in short the answer is no if you formatted your main drive, at least not directly. This has been asked several times over the last couple of years. If you did not make a direct backup, as recommended, to another device or make a point to store your X5 file on your host server or on the cloud, you'll have to rebuild.  Use your site (on the net) as a model and copy and paste where you can. Hope you have dual moniters or a large widescreen to work with. On the positive side if you needed to make big changes or redo your site, now would be the time, of course.

Let's see what one of the moderators/Incomedia has to say. They made need a few more details.

Regards Donald
