Folder Sync Tool - Table of Contents Folder Sync Tool Overview Starting from version 5.7.1 S3 Browser comes with a simple Folder Sync Tool allowing you to upload or download only new and changed files and thereby significantly optimize your bandwidth usage and save you time when performing backups to Amazon S3. Currently it works in one-way synchronization mode also known as mirroring, you can define the Source and Destination, which could be the Local Folder or the Bucket/Folder on Amazon S3. The minimal piece of synchronization is the File. If some part of the File was changed in the Source Folder, the entire file will be transferred to Destination Folder. S3 Browser uses file size and modification date to compare the files. An alternate comparison criteria is the file hash which works slower but allows you to detect file changes even if the modification date is incorrect.

- Include only changed files - S3 Browser will sync only file changes, new files will be ignored.
- Include both new and changed files - S3 Browser will sync both, new and changed files.
Propagate deletions - If you check this option, files that have been deleted in source folder, will also be deleted in destination folder. Use hashes to compare files - S3 Browser will analyze file content - calculate hash for the local files and compare it with the stored hash of remote files (hashes for remote files are stored in file metadata, remote files are not downloaded to calculate the hashes). This comparison criteria is slower than the Modification Date based approach but is most reliable way to compare the files and detect file modifications.
