Our installation software creates three directories for use by the first program of ours that you install. The top directory, just off the root, is C:\MWSOFT, the second is the program folder \SMITHMAT, and the last, (see about 14 lines below), is \MWDATA1. The tree structure is like what's shown below: However, once you have one of our programs, each additional install only creates a program folder, and a datasub-directory for that software program.

So, if you have all six programs, you will have one main directory, six program folders, and six sub-directories.

               

Here are the names, below \MWSOFT, of our various program folders and their corresponding data sub-directories:

               \SMITHMAT         \MWDATA1        SmithMatch
                \SCEPTRE            \MWDATA2         Sceptre
                \MSTRIP               \MWDATA3         MStrip+
                \OPTIMATC         \MWDATA4         OptiMatch
                \UTILITIE             \MWDATA5         Utilities+
                \SDATA                \MWDATA6         SData+

In the above sketch, your hard drive "Root" is C: Below, (or aside it)  are your system, program, and User created directories. We use the \MWSOFT directory for all of our main program .exe files. Its "path" on your hard drive is c:\mwsoft.

In the sketch, only one sub-directory named MWDATA is shown for simplicity. In reality, we use a separate data directory for each of our programs. If you have all six programs, you will have six sub-directories.

A significant advantage to this directory scheme is that, to access a file, you do not need to type a path, just a file name. Each of our programs "knows" that the data files are one level below the program folder.


For SmithMatch, support files are transferred into the \MWDATA1 sub-directory during the installation. The use of such files varies from program to program. OptiMatch uses three, while MStrip+ uses only one.

These files perform a number of functions. At a minimum, they record program usage, and whether or not you have an on-board clock. In the case of SmithMatch, this file records AR, your screen aspect ratio. In OptiMatch, the files store your preferred unit set, and changes made to algorithm variables.


These are impedance files that are used by SmithMatch, Sceptre, OptiMatch, and the SData+ programs. They are in simple ascii text format and contain three entries per line. These are frequency, Re (Z), and Im(Z). A maximum of ten lines of data are allowed.


This file type is only used by Sceptre, our frequency domain analysis program. Like a .IMP file, it is in simple ascii format. However, unlike a .IMP file, it can have any number of lines, and each line carries more data. Parameters like frequency, an s-data matrix, stability factor elements K & B1, gain, etc.


This file type is only used by SData+. It's a special type widely used in the industry and may contain s-data, noise data, or both.
