How to Tutorial & Support Center
Welcome to the IM-Magic How-To Center. Here, you can find guides that walk you through the process of shrinking a large partition, moving free disk space, reallocating it to another smaller volume, such as the system drive, and expanding the volume. You can repartition any drive without losing data.
For licensed users, contact support@resize-c.com if you still have questions about using the software after going through all our video/text tutorials, or if you encounter any technical problems.
For free users, contact sales@resize-c.com for a tailored guide. Please provide a screenshot of the Disk Management window along with your requirements so we can review your current disk configuration and provide more accurate guidance. To open Disk Management, right-click the Start icon and select Disk Management.
⚠ We strongly recommend using 'Copy Disk' or 'Copy Partition' to back up your disk or partition before making changes, even though Partition Resizer offers rollback and power-off protection against unexpected crashes. Additionally, please use the 'Defragment' and 'Optimize File System' features to ensure your disk is in good condition.
Note: Please be aware that formatting or wiping a partition, wiping data from a disk, or copying Disk 1 to Disk 2 can result in data loss. When copying Disk 1 to Disk 2, all existing data on Disk 2 will be deleted.
