There is sufficient room for file updates/growth and fragmentation rarely occurs.Īdditionally, if fragmentation does happen, most Linux filesystems would attempt to shuffle files and chunks around to make them contiguous again. ![]() ![]() Instead of placing files beside each other, each file is scattered all over the disk, leaving generous amounts of free space between each file. Linux's journaling filesystems take a different approach. As the space between chunks is limited, fragmentation will still occur over time. The NTFS leaves somewhat more room between the files, so there is room to grow. There is no room left for file growth or updates: In filesystems such as FAT and FAT32, files are written right next to each other on the disk. It was somewhat mitigated in NTFS and almost never happens in Linux (extX). This is particularly true for FAT and FAT32 filesystems. Fragmentation occurs when a file system updates files in little chunks, but these chunks do not form a contiguous whole and are scattered around the disk instead. ![]()
