Anyone know what, if possible, freeware can do this.. ie. folder on my pc1 and pc2. pc2 has all files/stored on it but pc1 has only some files and gets newer files which i want to pushed to pc2 when i update it. Also if i move files i don't wanna have duplicates or files dissapear. ie keep structure as pc1 unless it does not have it but don't delete from pc2 if the files don't exist on pc1
