You can use different options with the Robocopy command to achieve specific goals. These include "copy options" and "file selection options." Copy options include:

The public-good choice might include:

The following part will introduce how to sync folders bidirectionally with Robocopy. Note that the Robocopy command line is more suitable for users with some computer coding knowledge, which means you need to be careful with every step. If you are a beginner, we recommend a simpler way to sync folders. Todo Backup Free is a convenient method that allows you to sync folders bidirectionally with just a few clicks, ensuring that you have the files and folders on both sides without any hassle. (We also provide a detailed how-to guide in the next section.)

How to Use Robocopy for Two-Way Synchronization

You can achieve two-way synchronization of files using Robocopy by typing specific commands in the command prompt. This allows you to specify the source drive and the target drive, commanding the system to synchronize the files. Additionally, this tool supports one-way synchronization of folders.

If you need to do this regularly, it's best to create a batch file, so you can run Robocopy without having to type the command every time. Here's how:

Step 1. Type Notepad in the search bar, then hit Enter to open the Notepad app on your Windows machine.

Step 2: Paste the following list of commands into the Notepad window (make sure to replace the source and target drive paths with the correct paths on your computer):

Step 3. Press Ctrl + S to save the file. Make sure to name it with the .bat extension and save it in a location you can easily find.

Step 4. Next, double-click the downloaded .bat file from where it was saved. This will open a Command Prompt window showing the sync process between your selected locations. To sync files between the two spots anytime, just double-click this .bat file again. When it's done, feel free to close the CMD window.

An Easier Way to Sync Folders in Windows:

While Robocopy's bi-directional file sync works effectively, it has some limitations. For instance, it can't automatically sync files unless run through the Task Scheduler. A simpler way to achieve bi-directional file sync on Windows is by using a third-party tool like Todo Backup.

This free file sync tool lets you synchronize files in real-time, once, daily, weekly, monthly, or on-demand between two devices with its “New Sync” feature. Before kicking off the bidirectional sync process, you can choose the source and target folders. Aside from local disks, you can also sync files to external hard drives, network shared locations, or USB flash drives.

The tool also lets you filter out files that don't need to be synchronized by specifying them. You can also use Todo Backup to efficiently backup and restore files and folders.

Here are the main features of our Todo Backup tool:

• Two-way file synchronization from the left folder to the right folder.
• Real-time sync or scheduled sync based on daily, weekly, or monthly plans.
• Filter files you don't want to synchronize.
• Sync files to USB, external hard drives, networks, or NAS.
• File backup and restoration.
• Up to 250GB of free cloud storage space.

Todo Backup is the best alternative to Robocopy for two-way file synchronization. Be sure to download and install this software on your computer today. The steps to use this free file sync software are straightforward.

Step 1: Run the Todo Backup software and then click on the “New Sync” button at the bottom-left corner.

Click the Synchronize button.

Step 2: Click on Select sync folder on the left-hand side.

Step 3: Choose the folder you want to synchronize, then click OK. The source folder can be Desktop, My Documents, Favorites, Computer, Network, or a NAS.

Step 4. Choose the destination location for your synced files. You can opt for either a Two-Way Sync or a One-Way Sync, depending on your needs.

Tip: Tap Options to choose a sync schedule, including daily, weekly, event-based, or real-time syncing.

Step 5: Click Sync Now to start the sync.

Step 6. Wait for the sync process to complete; you can monitor its progress in the “File Sync” column in the upper-left corner.

Frequently Asked Questions (FAQ) about Robocoy Bidirectional Synchronization: 1. What is Robocoy Bidirectional Synchronization? - Robocoy Bidirectional Synchronization is a technology or feature that enables real-time or scheduled two-way exchange of data between two or more systems. This means updates made in one system are automatically reflected in the associated systems. 2. What scenarios is Robocoy Bidirectional Synchronization suitable for? - It's useful in various situations where maintaining data consistency across multiple devices or platforms is needed, like between cloud storage and on-premise servers, different databases, or between various business applications. 3. How do I set up Robocoy Bidirectional Synchronization? - The setup process can vary depending on the implementation but typically involves configuring source and target systems, defining which data fields to sync, and setting the synchronization frequency. Installing and configuring specific Robocoy software or services may also be required. 4. Can conflicts occur with bidirectional synchronization? - Yes, conflicts can happen if both systems modify the same data simultaneously. Robocoy might have built-in conflict resolution strategies, such as priority rules or manual user conflict resolution. 5. Does Robocoy synchronization support incremental syncing? - Usually, Robocoy supports incremental sync, transmitting only the data changed since the last sync, not the entire dataset each time, which helps improve efficiency and reduce network bandwidth usage. 6. Is Robocoy synchronization secure? - Security depends on the specific implementation. Typically, Robocoy employs encryption to safeguard data during transfer and may provide authentication and access control mechanisms to ensure only authorized users can access the data. 7.

Can I pause or stop Robocoy synchronization? - Yes, most implementations allow you to pause or stop the sync for maintenance or other operations. 10. Does Robocoy synchronization impact performance? - Sync operations can have some performance impact, especially when dealing with large amounts of data or frequent syncs. However, optimized sync algorithms and configurations can minimize this effect.

How do you mirror a folder with Robocopy?

You can achieve folder synchronization with the /MIR command in Robocopy, which ensures that the source and target folders have identical attributes. Here's how to use this command: 1. Open the Command Prompt (press Win + R, type "cmd", then hit Enter). 2. Navigate to the directory where Robocopy is located, typically at "C:\Windows\System32". Type "cd C:\Windows\System32" and press Enter to change the directory. 3. Input the following command, replacing `source_folder` with the path of the source folder and `destination_folder` with the path of the target folder: ``` robocopy source_folder destination_folder /MIR ``` 4. Press Enter to execute the command. Robocopy will start synchronizing the folders, removing any files or subfolders from the target folder that no longer exist in the source folder, while also copying all new and updated files. Please be cautious when using the "/MIR" option, as it will delete any files from the target location that are not present in the source location. It's advisable to back up your data before performing large-scale syncs or critical operations.

This command line uses the Robocopy tool in Windows to perform an mirroring copy. "Source Drive" is the path of the drive containing the content to be copied, and "Target Drive" is the path of the destination drive where the copy will be made. The parameter "/mir" stands for "mirror mode," which synchronizes the target directory, deleting files and subdirectories in the target that are not in the source, while also copying all new and changed files. Please note that using this command may result in data loss on the target drive as it aims to maintain exact parity with the source drive.

How can I automatically copy files from one folder to another?

You can use a reliable sync software like , which features file syncing that lets you choose the source and target folders for automatic file replication. It enables you to achieve real-time sync or schedule syncing to occur daily, weekly, or monthly. Make sure to download Todo Backup and try it out immediately.
