I am currently using a software program known as Allway Sync 7.1.2 Pro.

The software allows you to automatically track changes and additions/deletions of files. I use mine to ‘sync’ my flashdrive with my desktop. The software works flawlessly and easily and allows me to be sure that I will never lose a copy of my important files. As a special educator I have report cards, IEPs (legal student related documents), lesson plans and materials. I need to know that my years of materials won’t get lost or corrupted. Recently I actually fell in a lake while fishing and I had my flashdrive in my pocket! Fortunately the drive was undamaged, but if it was ruined I am secure knowing that my files are accurately saved throughout my workday on my desktop! I LOVE this program. The program lets you set up specific folders to ‘mirror’ or ‘shadow’. The software works well with removable drives, second hard drives, networks/servers, etc. Best of all the software is FREE up to a certain level of usage. I monitor around 3,000 files so I had to pay for it, but the program only cost me $20.00! A great value for such powerful and solid software!
