Are you confused between Linux vs Windows file systems? 

This guide will help you make up your mind.

Linux is generally more secure than Windows. Even though attack vectors are still discovered in Linux, due to its open-source technology, anyone can review the vulnerabilities, which makes the identification and resolving process faster and easier.

Both Windows and Linux use file systems to store data in an organized manner.

They organize disk-based files into a hierarchy of directories. Such directories are, "folders" and a whole hierarchy is a "file system" on both platforms.

Here at Ibmi Media, as part of our Server Management Services, we regularly help our Customers to perform Linux related queries.

In this context, we shall look into the conflict between Linux vs Windows file systems.

File system Hierarchy

It begins from the root directory, represented by the symbol /, which then expands into the sub-directories.

Windows includes various partitions which include directories; Linux places all the partitions underneath the root directory by mounting them in specific directories. In contrast, Windows uses the letter C as its root directory.

In Windows, during the boot process, it detects partitions and assigns a drive letter.

Under Linux, the system must mount partitions and devices during the boot process.

Linux vs Windows file systems

Windows makes use of FAT and NTFS file systems.

FAT: File Allocation Table (FAT) is the initial file system in Windows. The FAT file system was used in DOS and the three versions of FAT are FAT12, FAT16 and FAT32.

NTFS: NTFS, introduced with the Windows NT operating system, has much fewer file size limitations. Basically, Microsoft developed NTFS to compete with UNIX, by replacing the much more simple FAT.

In Windows, we don't have to worry about the file system, the default one is NTFS. Linux however, being built on a world of open source and differing opinions are not limited in this way.

On Linux, everything is a file. If something is not a file, then it is a process. Here, there is no difference between a file and a directory. A directory is simply a file containing names of other files. A variety of file systems can be sued with Linux.

Commonly used file systems are :

Minix: It is the filesystem in the Minix operating system, the first to run under Linux.

Ext: It is an elaborate extension of the Minix filesystem.

Ext2: It is the high-performance disk filesystem by Linux for fixed disks as well as removable media. It was designed as an extension of the extended file system (ext). ext2 offers the best performance (in terms of speed and CPU usage).

Linux also has "msdos" and "vfat" file systems for compatibility with Windows.

Each Windows file system has a File Allocation Table that states which disk blocks hold the topmost directory. On Linux, the equivalent on most filesystems is the superblock.

A Linux file system has multiple copies of the superblock physically saved on the disk. This provides redundancy in case of partial disk corruption.

In terms of recovery tools, Windows can use only limited tools, while there is a large number of UNIX-based recovery tools available for Linux file systems.

Unlike Windows, Linux is bootable from a network drive.

Linux has two kinds of major partitions called data partitions and swap partitions. Hence, we never run out of memory in Linux.

While Windows use FORMAT.EXE to format a disk, Linux use “mkfs” (“make file system”) in various specialist forms.
