Microsoft has released SyncToy 2.0 beta. Like its predecessor, SyncToy 2.0
is a free download that lets you synchronize files across multiple folders
and/or computers.
But there are a few new features under the hood:
* Dynamic drive letter assignment: change a drive letter and SyncToy
will automatically pick up on the change
* SyncToy now detects and synchronizes folder deletions, renamings, and
creation
* Exclude files based on names
* Filter by file attributes like read-only, system, or hidden
* Sync encrypted files
* Rename folder pairs
This is still beta software, so if you crave stability, you might want to
stay away. But SyncToy was already a pretty awesome tool for sharing or
backing up data. And SyncToy 2.0 seems to offer some nice improvements.
System Requirements
* Supported Operating Systems: Windows Vista; Windows XP
Microsoft .NET Framework v2.0
1GHz Intel P3 processor or equivalent
256MB RAM, 512MB RAM recommended
