Should I keep those files on my PC?

There's no need to do that.

They are the program files not tmp data. I suggest keeping the files!

Keep them on your PC!

Based on the file path, it is about Windows Virtual hard disk. I suggest keeping them on the computer.

Yes. They are important system files for virtual disk apps.

The files will be used by the Hyper-V app on Windows 11. You should keep them untouched!

Relevance: Are the files still useful or relevant to your current needs?

Storage Space: Do you have enough storage space? If not, you might want to consider deleting or archiving files you no longer need.

Safety & Security: Are the files sensitive or personal? If so, ensure they’re stored securely or consider deleting them if they’re not necessary.

Backup: Important files should be backed up. If you choose to delete them from your PC, consider storing them in the cloud or an external hard drive.

Do you have duplicates of the same files? Keeping multiple copies might be unnecessary.

Are they worth anything?

I wouldn't do that if I were you.
