How to Move non-system Files from SSD to HDD to Free Up Space?

Updated on December 23, 2025 by Admin to Free Windows Backup Software

When your solid-state drive (SSD) is running low on space but you want to maintain system speed, you can keep the operating system and frequently used programmes on the SSD, while moving large files and infrequently accessed non-system files to a hard disk drive (HDD). This guide will provide step-by-step instructions on how to safely migrate non-system files from the SSD to the HDD, precisely freeing up SSD space without affecting core system files, helping you achieve the best balance between speed and storage capacity.

Advantages and considerations of migrating non-system files from SSD to HDD?

Migrating documents, photos, videos and other non-system files from SSD to HDD not only frees up SSD space and improves data management efficiency, but also brings the following significant advantages:

  • Cost and Capacity Optimization: Given the higher unit cost of SSDs, allocate them for the OS and frequent applications. Use high-capacity HDDs for bulk, archival data, achieving an optimal balance of performance and storage economics.
  • System Performance Balance: Keeping the system and commonly used software on the SSD ensures fast booting and smooth operation. Meanwhile, transferring large files on the HDD helps reduce the read and write load on the SSD, lowering system latency.
  • SSD Lifespan Extension: SSDs have a limited write lifespan. Migrating frequently written files (such as temporary downloads and system caches) to the HDD can effectively reduce SSD wear and extend its usage time.

Before performing the migration operation, please review the following points carefully to prevent data loss or software issues caused by operational mistakes.

  • Check Available Disk Space: Press the "Win + E" keys to open File Explorer, navigate to "This PC", and check whether the remaining space on the HDD is sufficient to accommodate the data to be migrated. If the HDD is new and shows as "Not Initialized" in Disk Management, right-click it and select "Initialize Disk".
  • Select Content for Migration: It is recommended to migrate files that do not affect system performance and take up a lot of space, such as documents, photos, videos, music, and compressed files. After moving them, organize the files into appropriate folders for easier management.
  • Avoid Migrating System Files: Do not manually migrate important files from the C: such as Windows Files, Program Files, Program Files (x86), AppData and others. These are usually tied to the OS and applications; moving them may cause program damage or boot issues. Keep them on the SSD.
  • Create a System Backup: Before performing any major operation, it is recommended to create a full system backup. This allows you to quickly restore the computer to its pre-migration state in case of any issues, effectively safeguarding both data and system security.

How to Move non-system Files from SSD to HDD to Free Up Space?

The following are the steps to move non-system files from SSD to HDD, divided into four parts: new HDD initialization (optional), system backup, system settings migration, and file migration.

1. Initialize the New HDD

Step 1. Install the HDD into your computer (ensure your laptop supports dual drives) and power on. In Windows, right-click the Start menu and select Disk Management.

Step 2. If the new HDD is listed as "Not Initialized", right-click it, select "Initialise Disk", and choose GPT or MBR as your required partition style.

Step 3. Right-click on the unallocated space, select "New Simple Volume", and follow the on-screen wizard to set up the partition.

* Tips: If the hard drive is not new (pre-used) and contains existing data, you can typically skip the initialization part.

2. Create a System Backup

Step 1. Download, install and run Hasleo Backup Suite. Click the "Backup" button in the navigation bar, then select "System Backup" from the action area.

* Tips:

  1. Task name: Specify a task name so that you can quickly find and manage your backup task later.
  2. Description: Briefly describe the purpose of the task and any other relevant information.
  3. Destination: Modify the destination path where the backup image files will be stored by clicking the folder icon.
  4. Backup options: Advanced backup settings. For more details, please refer to Backup options.
  5. Backup schedule: Set up backup schedules to automatically perform your backup tasks on a regular basis. For more details, please refer to Backup schedule.

Step 3. After clicking the "Continue" button, Hasleo Backup Suite will begin backing up your Windows operating system to the HDD. Note that the duration depends on the amount of data, so please wait patiently.

* Tips:

  1. Priority: Specify a priority for the backup process. A higher priority allocates more CPU time to the backup, which may cause other programs to run slower.
  2. Check image: Verify the integrity of the backup image files upon completion of the backup process.
  3. Power plan: Perform the power management action after the backup is complete.

3. Migrate System Settings

Step 1. Press the "Win + I" keys to open Windows Settings. Select "System", then click "Storage" in the left-hand navigation bar.

4. Transfer Files

Step 1. Create the target folders on your HDD. Press the "Win + E" keys to open File Explorer, and navigate to C:\Users\YourUsername.

click c:\users\useryourname

Step 2. Right-click the folder you want to transfer, select "Properties", and go to the "Location" tab. You will see the current path. Click "Move" and choose the destination folder you created on the HDD. Click "OK".
