Windows File Sync

Although it’s usually not my preferred OS, I had to implement a file synchronisation (synchronization) on a Windows XP (R) system.
The user wanted a real sync between two folders (Hard Disk and USB Drive).
Means: When a file is deleted/created/renamed on the harddisk, it should be deleted/created/renamed on the USB drive, too – and the other way round..

What I found so far:
Allway Sync (nice gui, easy to use, limited to 20.000 files per month [freeware edition])
SyncToy (from Microsoft (R), not tested yet)

Any better ideas?

German government forbids security tools

Maybe only interesting for german readers and security specialists.
The german government accepted a law that forbids the usage of programs that can be used by hackers and crackers in illegal activities. What they obviously forgot is the simple fact, that you have to use some of these programs to prevent your system from being hijacked. Or what is more probably:
People without any technical knowledge decided once again what is good for us.
Thank you b**ches!
