Foxerly Partition Manager
Extend drive C and resize partitions without losing data
Drive C is full while drive D has plenty of room? Foxerly Partition Manager extends drive C even when the recovery partition is in the way, resizes, creates and formats partitions, and converts the Windows disk from MBR to GPT, without deleting your files.
- Extend drive C
- No data loss
- Windows 11 and 10
What Foxerly Partition Manager does
Fix and extend drive C
When the recovery partition blocks drive C, it is moved to the end of the disk so C can grow into the free space.
Create, format and label
Set up a new drive, create and format partitions in NTFS, FAT32 or exFAT, and change drive letters and labels.
Convert the Windows disk to GPT
Converts the disk Windows runs from from MBR to GPT with Windows’ own MBR2GPT, keeping your files, before moving to UEFI and Windows 11.
Initialize new disks
Set up a brand-new disk as GPT or MBR, ready for its first partitions.
Nothing happens until you apply
Every change is shown in a preview first and queued. Your disk is only touched when you press Apply.
How to use Foxerly Partition Manager
- 1
Pick the disk
Every disk and partition is shown as a bar, with the used and free space on each.
- 2

Apply
Review the list of pending operations and apply them. Some changes to the Windows drive finish during a restart.
When Foxerly Partition Manager helps
Partitions are usually set once, when a PC is new, and then stay the same long after your needs have changed.
Low disk space on drive C
Take free space from another partition and add it to C, without reinstalling Windows.
Preparing for Windows 11
Convert the system disk from MBR to GPT, which UEFI and Secure Boot require.
Setting up a new drive
Create, format and label partitions on a new internal or external disk.
Tidying up old layouts
Remove old partitions you no longer need and give the space back to the partition next to it.
Why Windows will not extend drive C
Windows Disk Management can only extend a partition into unallocated space that sits directly to its right on the disk. On most PCs drive C is followed by a recovery partition or by drive D, so the Extend Volume option stays greyed out, even when there is plenty of free space elsewhere.
When the recovery partition is what blocks drive C, Foxerly Partition Manager moves it out of the way: it removes it, extends drive C into the free space and creates the recovery partition again at the end of the disk. Your files on drive C stay where they are.
Resizing is safe when it is done carefully, but it does move data around. Back up anything important first, and keep a laptop plugged in while changes are applied, because a power cut in the middle of an operation is the one thing that can cause damage.

Foxerly Partition Manager questions
Can I extend drive C without losing data?
Yes. Foxerly Partition Manager adds unallocated space to C, and moves the recovery partition out of the way when it blocks C. Your files and Windows stay as they are.
Why is Extend Volume greyed out in Disk Management?
Windows can only extend into unallocated space directly after the partition. If a recovery partition or drive D is in the way, the option is unavailable. Foxerly Partition Manager can move a recovery partition that is in the way. To use space from drive D, shrink or delete D first.
Is resizing partitions safe?
Yes, when done properly. Every change is previewed before it is applied. As with any disk operation, back up important files first and keep laptops plugged in.
What is the difference between MBR and GPT?
They are two ways of organizing a disk. GPT is the modern standard needed for UEFI and Secure Boot, which Windows 11 requires. MBR is the older style.
Can I convert MBR to GPT without losing data?
Yes, for the disk Windows runs from: it uses Windows’ own MBR2GPT, which keeps your files. Afterwards the PC starts in UEFI mode. Other disks are converted when they are empty.
Does it work on external drives and SSDs?
Yes. It works on internal and external HDDs and SSDs, USB drives and memory cards.
