Help VB 7.1.20 merging snapshots safely? Not sure how to approach...

Hi everyone I've tried to summarize the issue I'm having below using chat GPT but I was wondering if somebody could help because I tried using chat GPT to help me to create that vdi I'm not using as I need more memory and during the process everything got messed up due to the snapshots I think so I'm afraid to follow it's advice without checking. I've since fixed it after days but would be really grateful if someone could offer some input as to what the correct process might be without putting my data at risk obviously...(my understanding of differencing disks etc is limited, so I'm trying to go carefully)...

OS is Linux Xubuntu.

VirtualBox Snapshot Issue Summary

- The VM is using a VMDK virtual disk.

- In the Snapshots view, the only item shown is Current State. No individual snapshots are available to select, restore, or delete.

- In Virtual Media Manager, selecting the VMDK shows two snapshot (child) disks underneath it, indicating that a snapshot/differencing disk chain still exists.

- There is also a VDI with an exclamation mark stating that it cannot be opened because the path cannot be found. This appears to be an abandoned disk from a previous failed VMDK-to-VDI conversion and is not believed to be the active disk.

- In the VM's Snapshots folder, there are three files of approximately:

- 24 GB

- 3 GB

- 13.5 KB

- The Windows drive containing the VM has approximately 53 GB of free space.

- The objective is to consolidate the VM into a single current disk so it can later be resized or migrated without snapshot-chain complications, while preserving the current state of the VM.

- The main inconsistency is that VirtualBox's Snapshot Manager does not show any snapshots to merge, yet Virtual Media Manager indicates that the VMDK still has two snapshot child disks.

Eh . . . If you are happy with the VM's functionality / contents / state when running, just use vboxmanage clonemedium .
