Synchronize Laptop and Desktop
I have two computers running on windows, one at work and one at home, I take a copy of the documents that I work on to home and keep working on them when I'm home. So my problem is that I need a software to backup these documents for me on my external hard at the end of the day at work and when I take it home I can synchronize my documents with it, so I'll have the same modifications on my documents at home as I have done at work.
appreciate any help.
