THE FIRST THING YOU NEED TO DO IS IDENTIFY HOW YOU BACKED UP YOUR FILES IF YOU USED A SOFTWARE YOU WILL NEED TO RETRIEVE THOSE FILES USING THE SOFTWARE MOST OF THE TIME SOFTWARE RENAMES AND RE ARRANGES EVERYTHING FOR ITS USE MAKE SURE YOU RETRIEVE THE FILES AND VIEW TO CHECK IF THEY ARE THERE IF IT WAS DONE USING A SYNC SOFTWARE YOU MIGHT HAVE LOST THE DATA BECAUSE SYNC SOFTWARE DONT ACTUALLY BACKUP
