NTFS, or the New Technology File System, is a proprietary file system developed by Microsoft and is the default file system for Windows operating systems. It was introduced with Windows NT 3.1 in 1993 and has been continuously improved and updated since then. NTFS is a journaling file system, which means that it keeps track of changes made to the file system and can recover data in the event of a system crash or power failure. NTFS also supports file encryption, compression, and quotas, and it can be used on both local and network drives.
There are several ways to check if a drive is formatted with NTFS. One way is to use the Windows File Explorer. Right-click on the drive you want to check and select “Properties” from the menu. In the “General” tab, the “File system” field will show the file system type of the drive.
