You are permitted to try this software on your system (for 30 days) without any cost or obligation. Payment is required if you find this software to be useful or if you wish to continue using this software beyond the evaluation (trial) period. This product is provided at no charge to the user for evaluation. The purpose of an evaluation version is to provide computer users with quality software on a try before you buy basis, however payment is still required for continued use of the product.

This method allows you to try out all the features in SyncBelt to confirm that they work to your satisfaction before purchasing a license of use.

The evaluation version is the same as the full version of the product: no nags, no disabled features.


Create projects to manage your synchronization folders. SyncBelt allows you to create up to 15 projects.

To create a new project, click and enter your project details.

First, we will configure the folder of Origin, on the left side of the screen:

  • Decide if you wish to sync from a local or remote folder, by clicking on the Protocol box. Select either Local, SFTP or FTP.
  • Enter the folder from where files will be copied.
  • If the folder is a remote server, enter the server address and port, with username and password, if required. Click the Test Connection button to check your server details.

Now, move to the right side and repeat the same process to configure the folder of Destination. Click Save when finished.

Your first project is now ready. Check the Project Summary at the top. By default, files are synchronized by modification date, no destination files are deleted and no files are skipped. If you wish to modify the defaults, click on Edit and then click Advanced at the bottom of your project.

Advanced options allow you to modify your project's defaults:

  • Determine if a file has changed by: allows you to set the file comparison method to by file modification date or file size, or alternatively do not compare and always copy.
  • Orphaned files in destination must be: allows you to decide if destination files that do not exist in origin should be deleted in destination, or ignored.
  • Skip files matching the following rule: allows you to skip files that match the chosen rule.

After making changes to your project, check again the Project Summary at the top to make sure everything is configured as desired.

If you need to delete a project, open the Edit menu, select Delete and click Confirm.


In order to synchronize a folder, first you'll need to create a project. Once you have a project, open it and click Start at the bottom to begin.

The synchronization process has 4 different steps:

  • Simulation: during this step, SyncBelt executes your project and compares origin and destination files. Nothing is actually done, yet.
  • Review: on this step, SyncBelt is ready to sync and shows you a list of files based on the simulation results. Now, you know what will exactly happen with each individual file and still can make changes. When you are ready, click Sync Files.
  • Syncing: on this step, SyncBelt synchronizes files based on the selected data on the previous step.
  • Results: on this final step, SyncBelt shows you a brief summary of what happened. For more details open the Report menu and click on View Report or Export as CSV.

The Review step is the most important one. Double-check the list of files to make sure the synchronization process will proceed as expected. Files are checked or unchecked based on their resolution:

  • Checkbox: Indicates if the file should be copied/deleted (checked) or ignored (unchecked).
  • File: Name of the file, including path.
  • Size: File size, including icons to indicate if the file is bigger in Origin (▲), smaller in Origin (▼) or equal (=).
  • Resolution: A short sentence explaining what will happen with the file, which can be overridden: checked files will be copied/deleted, unchecked files will be ignored.

For resolutions, the source file (origin) is always the reference. Take this into account when interpreting the presented information.

  • Unmodified: Origin and Destination files are equal. Origin file will not be copied. Check to override resolution and copy anyway.
  • Orphan: Destination file/folder does not exist in Origin. Destination file/folder will be deleted. Uncheck to avoid deletion.
  • Modified: Origin file is different than Destination's and will be copied. Uncheck to skip.
  • New: Origin file does not exist in Destination and will be copied. Uncheck to skip.
  • Skipped: Origin file will be skipped based on a rule. This resolution cannot be overridden. Revisit your rule to obtain a new resolution.


During synchronization, you'll be able to compare files before proceeding which allows you to see specific differences between files.

After the simulation process has ended, you'll find this symbol to the right side of some files. These are the requirements in order to be able to compare files:

  • Different size/time: files must have a different size or modification time.
  • Text extension: only text files can be compared.
  • 1MB: only files smaller than 1MB can be compared.

Rules & Permissions

Rules are helpful to skip files during synchronization. For example, you may want to skip .tmp files or .git folders.

To create a rule, click on the Rules link at the top of the screen and then click on the New Rule button. Rules must include a set of conditions:

  • File size: this condition is triggered when a file is equal/greater than/less than a specific number of bytes/KB/MB/GB.
  • File name: this condition is triggered when a file name is/begins with/ends with/contains a specific text.
  • Folder name: this condition is triggered when a folder name is/begins with/ends with/contains a specific text.

By default, rules require any condition to be met in order to be triggered, but you can change it to all conditions, at the top of your rule. Use the X button at the right side of each rule to remove it.

Unix-style permissions can be optionally applied to files after synchronization. Permissions only apply to remote servers and can be configured from the Rules screen. Use the X button at the right side of each permission to remove it.

To create a permission, click on the Rules link at the top of the screen, then click on the Permissions tab and then click on the New Permission button. Enable or disable permission settings by clicking on each button.

  • Permissions are applied based on file extension.
  • By default, files synchronized via FTP/SFTP have the following permissions: User: Read & Write, Group: Read, World: Read.
  • By default, folders synchronized via FTP/SFTP have the following permissions: User: Read & Write & Execute, Group: Read & Execute, World: Read & Execute.
