Native File systems
Linux supports a large number of file systems; however, there are two that are most commonly used, and they are the only two offered by the MEPIS installer for use. They are:
Obviously, most people will wonder which one is the best. There really is no definitive answer, and an average desktop user probably will never know the difference either way. For advanced users, each system offers slightly different features and performance in different circumstances.

"Foreign" File systems
MEPIS also supports a variety of filesystems associated with other operating systems; the most notable are:
- NTFS - The Windows NT/2000/XP/Vista file system. MEPIS 6.5 & later have read/write support for NTFS using the NTFS-3g drivers. MEPIS 6.0 and earlier install with read-only support but can be modified with Captive to support NTFS write.
- FAT32 - The Windows 98 filesystem; still popular for use on removable devices over 2GB. Also commonly used as a "shared partition" between Windows and Linux on a dual-boot computer.
- FAT - A.K.A. FAT16 or DOS filesystem. Commonly used on small removable devices (floppies, flash drives, etc). Has a partition size limit of 2 GB.
- HFS/HFS+ - Apple file system. HFS is pre-OSX, HFS+ is the standard file system for OSX.
