loads

folder and all the folders below it are no longer contained on the LMF

CD as of LMF 2.9.0.0. When installing LMF software on a system that has never

contained LMF software before, the user will need to create these folders manually .

When installing a new version of LMF onto a PC already containing LMF software,

any existing folders will be unaffected.

WinLMF Directory

The CDMA LMF installation program creates the default home directory , c:\wlmf , and installs the

application ﬁles and subdirectories (folders) in it. Because this can be changed at installation,

the CDMA LMF home directory will be referred to with the generic convention of:

<x>:\lmf home directory>

Where:

<x> = the LMF computer drive letter where the CDMA LMF home directory is located.

<lmf home directory> = the directory path or name where the CDMA LMF is installed.
