FolderShare.com - sync files, sync folders, transfer files, share files, web download, access files anywhereThis is an awesome tool for keeping folders sync'ed on separate machines. First off, here is the way I normally keep my my worked sync'ed and backed up. I have a favorite sync tool called Directory Toolkit that I run at work that syncs my documents on my office machine to an external hard drive (or sometimes with my laptop). I then take that external drive home (or laptop) and sync with that computer. Therefore, I have three hard drives that contain all of my work within a few days of use. A couple disadvantages to this are that (1) I might still need access to my files from a third computer somewhere and then I would have to deal with ftp or remote desktop or something like that and (2) this process is a little tedious. However, FolderShare allows real-time syncing! I checked this out using Remote Desktop just to see how immediately it would sync changes I made on my office machine would affect the home computer, and it was quick! FolderShare has a few limitations, but workarounds exist. For example, it limits folders to 10,000 files. For me, I just set up individual syncs for each of the subfolders that contain less than 10000 files or I keep zips of the big stuff. Also, it caps files to 2GB. I don't really need to sync 2GB files, but there is no workaround I know except splitting files with a 3rd party utility.
