WinDataReflector is a free lightweight file synchronization and backup tool that wraps up fast file comparison and transfer algorithms into a simple and clear interface that offers you visual comparison of files and folders before synchronizing and backing them up and support for two way synchronization with fully customizable rules.
Two way synchronization with fully customizable rules
Changes made to either left or right folder are mirrored to the other folder making them identical and you can also configure WinDataReflector to only propagate certain changes.
Automatic synchronization and backup with built in scheduler
Schedule any task to run automatically at certain times of day or days of week and at specific intervals.
Run multiple tasks simultaneously in tabs
View and run several tasks at the same time in separate tabs.
File and folder filtering using Regular Expressions or regular search
Exclude any directory, file name, file extension or exclude files that match regular expressions on the exclusion list.
Support for NTFS file permissions (ACLs/DACLs)
NTFS file security information and access rights can be copied to destination files and folders.
CRC comparison and verification
In addition to timestamp and size comparisons WinDataReflector also supports using CRC (Cyclic Redundancy Check) checksums to compare files and verify their integrity after copying.
Supports backing up files to ZIP archives in two modes: overwrite existing or create new timestamped archives for each backup.
