Summary: Have you ever used the file system HPFS? What is HPFS and where do we use it? Today, iBoysoft will simply introduce HPFS to you, including the differences between HPFS and NTFS.
HPFS, short for High-Performance File System, is a file system developed by IBM in collaboration with Microsoft for the OS/2 operating system.
HPFS was designed to overcome the limitations of FAT by offering better support for larger files, long filenames, and improved performance. While its relevance has declined with the rise of newer file systems like NTFS, HPFS remains widely used.
When I wanna format my drive, I noticed that there are many choices like NTFS/exFAT/HPFS. What do they work? What are the differences? -reddit.com
Keep reading, we will give you the answers.
The Features and uses of HPFS
High-performance file system brings many advanced features to our lives and work, and it is commonly used in many areas. The main features are summarized here:
- Supports longer filenames: Unlike FAT, which restricted filenames to 8.3 characters, HPFS allowed filenames of up to 255 characters.
- Has efficient storage: HPFS used 512-byte sectors and allocated disk space more efficiently, reducing fragmentation.
- Owns optimized file management: Files and directories were stored in a B-tree structure, allowing faster access and reduced seek times.
Therefore, HPFS was primarily used in OS/2 systems, catering to professional environments requiring reliable performance. It also found applications in handling databases and other large file-oriented workloads during its prime.

How does HPFS work?
HPFS employs a B-tree structure for organizing directories and files, which significantly improves read and write speed. Here's how it functions:
- Metadata management: HPFS stores metadata, such as file names, sizes, and timestamps, in a structured format that is quick to retrieve.
- Sector allocation: It minimizes wasted space by allocating disk sectors dynamically based on file size.
- Error recovery: The system integrates basic error detection and correction mechanisms to ensure data integrity during crashes or power failures.
These design choices allowed HPFS to provide a smoother and more efficient experience compared to some other file systems.
The advantages and disadvantages of HPFS
Let's see the pros and cons of the HPFS file system here:
| Advantages | Disadvantages |
| Faster file access | Lack support on modern systems |
| Support for larger files and volumes | Complex to recover and repair data |
| Minimize file fragmentation | More outdated |
What is the difference between NTFS and HPFS?
Maybe you think HPFS is less useful than other file systems like NTFS, here is a table comparing HPFS vs NTFS:
| Feature | HPFS | NTFS |
| Year | 1988 | 1993 |
| Compatibility | OS/2 | Windows (NT and later) |
| Security | Limited | Advanced |
| File size support | Up to 2GB | Up to 16EB |
| Recovery features | Basic | Advanced |
Therefore, NTFS surpasses HPFS with features like journaling, enhanced security, and greater scalability, making it the preferred choice for modern systems.

HPFS file system marked a significant leap forward in file system technology, offering solutions to the limitations of FAT. While it has been replaced by more advanced systems like NTFS, its contributions to the development of modern file systems remain influential.
