As with most other versions of Windows, the Windows 11, 10, ... file system is the NTFS (New Technology File System)!
Info:
The Windows 11, 10, 8.1 and other MS Server operating systems primarily use NTFS. The file system is also supported by other operating systems such as Linux and BSD. Unfortunately, macOS only provides read-only support for NTFS.

Disk Management:
The first and probably easiest way to know the status of your or more disks is to use Disk Management . However, opening Disk Management in Windows is also a pretty straightforward task, and even if you have not had Windows 10 training before, if you've never had anything to do with Disk Management, you should be familiar with Disk Management.

NTFS and FAT!
The FAT file system was the primary file system in the older Microsoft operating systems and was replaced by NTFS in 2005. However, all versions of Windows still support FAT, also known as FAT32, and there are many drives that are formatted with FAT, or FAT32, and not NTFS. The exFAT file system is a modern file system, but it was primarily designed to format the problematic drives, such as flash drives.
