Usb stick was 128gb but now is 114gb

I have a SanDisk Ultra 3.0 128GB flash drive
When I formatted it and deleted the volumes I created, now the flash drive only has 114GB.
I don’t know if this is a forum topic but I would appreciate your help

Hi @Kosiarz5650

Why did you format it? Was it used? The factory format is exFAT, what format did you use?

To remove files/folders from a new drive that you don’t want the Windows’ File Explorer’s Delete key works.

First, open Disk Management and check if there’s any unallocated space on the drive. If you find some, right-click the drive and create a new partition to use the full space. If that doesn’t help, try reformatting the drive by right-clicking it in Disk Management, choosing Format, and selecting exFAT as the file system.

Thanks @johnjacobb40 for sharing the solution. It works.
