Does NTFS Have A File Size Limit?
By Tobias Geisler Mesevage
Windows-supported operating systems rely on one of two different types of file systems: File Allocation Table (FAT) or New Technology File System (NTFS).
The file systems use a set of rules to control how data is stored and retrieved on a storage device. While both FAT and NTFS were created by Microsoft, each has different benefits and disadvantages related to compatibility, security, and flexibility.
In this article, we will discuss the benefits of the NTFS file system and whether NTFS has a file size limit.
NTFS vs. FAT
Microsoft created the File Allocation Table file system in 1977 and it is considered the most straightforward, zero frills type file system supported by Windows NT. It is the older of the two file systems and therefore isn’t as efficient or advanced. However, it does offer more compatibility with other operating systems and removable storage devices.
A FAT gets utilized most often for removable storage devices, such as digital cameras, Smart TVs, and other portable devices.
Microsoft created the New Technology File System in 1993, and it is now the most widely used file system in Windows.
NTFS was meant to become a replacement for the FAT file system, designed to improve upon FAT by increasing performance, reliability and disk space.
- Very large files
- Different file permissions and encryption
- Automatically restores consistency by using log file and checkpoint information
- File compression when running out of disk space
- Establishing disk quotas, limiting space users can use
While some users still take advantage of FATs simplicity, NTFS’ benefits are more far-reaching.
Benefits of NTFS
NTFS offers different enhancements and increased security:
- Fault Tolerance: NTFS automatically repairs files/folders in the case of power failures or errors.
- Security: NTFS allows you to set specific permissions to local files/folders.
- Compression: NTFS allows for individual compression of files and folders so you don’t slow down the system.
- Compatibility: NTFS is compatible with operating systems back to Windows XP. For Mac OS users, however, NTFS systems can only be read by Mac, while FAT32 drives can be both read and written to by the Mac OS.
NTFS File Size
The maximum theoretical limit on the size of an individual file is 16 EiB minus 1 KB. There is no realistic file-size or partition size limits.
Below are the NTFS limits:
- Maximum disk size: 256 terabytes
- Maximum file size: 256 terabytes
- Maximum number of files on disk: 4,294,967,295
- Maximum number of files in a single folder: 4,294,967,295
