Which file system type is likely preventing accounting users from encrypting their files?

The likely reason accounting users are unable to encrypt their files is due to the FAT32 file system. FAT32, or File Allocation Table 32, is an older file system that does not support file-level encryption features. It was designed for compatibility across various platforms and devices, which means it lacks many advanced features found in more modern file systems.

Unlike NTFS (New Technology File System), which supports various security features including file system-level encryption (EFS), FAT32 does not provide any built-in mechanisms for encrypting files. This limits the ability of users, like those in accounting, to encrypt sensitive financial data stored on volumes formatted with FAT32.

In contrast, file systems like ext4, ZFS, and even QFS (Quilted File System) are more modern and support various advanced features such as security policies, which can include encryption capabilities. Therefore, in an environment that requires sensitive data encryption, using FAT32 would hinder the users' ability to secure their files properly.
