- OpenZFS
- NTFS
- ext4
- Btrfs
-
ETERNAL is NOT a misspelling of External. The file system supports both internal and external drives, and also is meant to last an eternity.
-
A 128 bit or better processor is required to operate the file system, a 256 bit processor isn't required, but is recommended. The file system cannot run on 127 bits or lower, which includes 64 bit, 32 bit, 16 bit, 8 bit, etc.
-
This file system is designed for the QMeadows operating system, but can run on other Linux distributions once you add support for it
-
Some people don't say the
FSline when referring to a file system by name. On 2022, August 23rd, I escaped confusion regardingBtrfsbeing referred to asBTR, which originally made me thinkBTRandBTRFSwere 2 different file systems, which led to major confusion when I couldn't find anything on theBTRfile system, which doesn't exist. When referring to QMEFS, please also mention theFSpart of the name to avoid confusion.
In short, Don't refer to it as
QMEorQM
