    Win 7 install, Not at all like what was shown in the screenshots when you click the icon that installs to the start menu (RealtimeSync). It Only gives command line option. You will have to go to the program folder and click the green (FreeFileSync) exe file to get the full initial program setup. Then it should be all good

    use to use MS synctoy but it's so out of date you can see there is no future in it. looks like sync center is the way to go for MS native but I have Windows 7 Home so I don't have that choice. anyway, came across this, judged it on downloads per week and gave it a go. really impressed, easy to setup and with just a little reading you can get it to do realtimesync with realtimesync that comes with it! looks like it's maintained well and kept up to date (big plus) and I like the way it can use Windows Shadow Copy for locked files. great stuff and thanks!

    -Pros- • Option for portable install • Support for multiple source and destination paths • VERY fast comparison • Good view of changes that are going to be / are being made (tree views with percentage bars, graphs of copying process, taskbar progress meter, etc) • Support for environmental variables in paths • Support for drive labels over letters in paths • Support for more than one concurrent instance -Cons- • Bit of a learning curve due to the unintuitive UI (exclusions have to be relative to the source path, "Item exists on left / right side only" column is always on the left, the difference between global and local filters is not obvious, etc) • No option to keep versioning in the same folder - it has to be a single, user-defined folder • Custom synchronisation is not customisable enough (actions are catagory-sepecifc, for example) • Not smart enough to know only the filename changed • No tree view for comparison results tables • Doesn't take files that will be deleted into consideration when warning about free space • No current log of sync process, only the current action. Although, there is one post-sync

    Nice tool, like pro app but I miss one feature: background service. However I think it is best free file sync.
