To create a new mfs file you can use
m_touch <filename> but you have to be sure that you are in a
multidirectory.
after creating the multi file just do a
cat <multifilename> you will see how many partitions are in
that.
You should have a multifile system with 4 way and 8 way
depth to create multifiles of according depth.

m_mkfs can be used for creating desired mfs file.
But a developer never creates any MFS path it is done by the Abinitio administrator. There are different mfs path parameters created by administrator like.
AI_MFS : Default MFS path.
AI_4way_MFS : for creating 4-way mfs file
and so on.
we only use the required path in the o/p file URL to create desired mfs file.

Answer / sohanvarma
create a new file--> m_mkfs.
To convert 4 way to 8 way partition we need to change the
layout in the partioning component. There will be seperate
parameters for each and every type of partioning eg.
AI_MFS_HOME, AI_MFS_MEDIUM_HOME, AI_MFS_WIDE_HOME etc.
The appropriate parameter need to be selected in the
component layout for the type of partioning..
