On this note, do you still need clarification about what precisely a file system is in the first place? Here is the basic description.

File systems are types of data structures within operating systems that help monitor all existing files. Users can easily find the files within their storage devices through this.

  • FAT32:

The FAT32 (File Allocation Table32) is Microsoft's latest version of the default file system for Windows 95 OSR1 or M-DOS 7. It holds drive sizes of 2TB-16TB (+64kb clusters), which is helpful for bigger hard drive performance.

  • EXT3:

The extended file system 3 or EXT3 was mainly prepared for Linux kernel-based devices. This journaled file system works as a default file system for Linux distributions, supporting 16GB max file size and 3TB max file-system size in 1KiB block size and counting higher. 

  • EXT4:

As an EXT3 successor, the EXT4 file system has higher size limits, with volume support of a maximum 1EB size (or approximately 1048576 TB). The single files can range in size up to 16 TB. You can click the link below to get more details about EXT3/4:
