erify the Partition and File System

After extending the disk space in Disk Management, you need to ensure that the partition itself is extended to use the newly added space. Sometimes, the partition might not automatically expand to use the unallocated space.

  • Open Disk Management (diskmgmt.msc).
  • Check if the partition on the disk has been extended to include the newly allocated space. If it hasn't, you'll need to extend the partition manually.

2. Extend the Partition Using Disk Management

If the partition hasn't automatically extended, follow these steps to manually extend it:

  • Right-click the C: drive (or the drive you're extending) in Disk Management.
  • Select Extend Volume.
  • Follow the prompts to extend the partition to use the unallocated space.

After completing this, the File Explorer should show the updated disk size.

3. Extend the Volume Using DiskPart (If Needed)

If you're more comfortable with the command line, you can use DiskPart to extend the partition:

  • Open Command Prompt as Administrator.
  • Run diskpart.
  • Type list disk to identify the disk you extended.
  • Select the disk by typing select disk X (where X is the number of the disk).
  • Then, type list volume to identify the volume (the partition) you want to extend.
  • Select the volume by typing select volume X (where X is the volume number).

Check File System Integrity

If the partition is extended but the space is still not reflected, there may be an issue with the file system not recognizing the new space. You can try running the following command to check and repair the file system:

  • Open Command Prompt as Administrator.

  • Verify Network Shares

    After successfully extending the partition, verify if your network shares (especially the one that's showing as 280GB) are properly configured to use the extended space.

    • Check if the shared folder is still located on the correct drive.
    • If you're sharing the entire drive, it should automatically reflect the new size, but if you're sharing specific folders, ensure that the files within the folders are being managed properly.
