How to Synchronize Two Folders on Windows

Steps

1. Compare the two folders: choose Files | New Comparison (Ctrl+E), select Compare Directories, pick the folders, and click Compare. Changed files and files found on only one side are highlighted, and the Time column shows which copy of a changed file is newer.
2. Choose Edit | Synchronize Directories and pick the Direction:
   • First -> Second or Second -> First makes one folder a copy of the other, for example to update a backup
   • Bidirectional copies in both directions, so each folder gets the other's new files and the newer version of every changed file
   Under Synchronization options, choose whether to copy missing files and empty folders, and whether to replace existing files. With Only if newer, an older file never overwrites a newer one; Bidirectional always works this way. Use directory comparison filters leaves out the files your comparison filters exclude.
3. Click Preview to see every file that will be copied, where it comes from, and where it goes. Clear a check box to leave that file out.
4. Click Synchronize and confirm. The log lists each copy as it is made, with the number of new and overwritten files and any errors.
5. Close the log and let ExamDiff Pro compare the folders again (or choose Directories | Re-Compare). After a bidirectional synchronization, all files are the same.
