Overview
Freemem.exe is a moveable, popup, free memory display compatible with
Microsoft Windows 2.x and 3.0.
- If EMS is detected the amount free is displayed along with
conventional memory free. A plus sign separates conventional from
expanded, with expanded on the right.
- Freemem will keep itself on top of other windows so that it is always
visible.
- With the left mouse button, click and drag Freemem to move it to the
desired location on your screen. This position will be stored
in the current WIN.INI for subsequent startups. (The default startup
position is the upper left corner of your screen.)
- Add Freemem to the LOAD or RUN line of your WIN.INI.
- As a Windows applications developer I have found freemem to be a
useful tool for detecting memory managment problems within applications.
Since FREEMEM remains visible, tracking memory usage is simplified.
- The option to compact global memory every 1 to 99 seconds is
usefull for windows developers who want to test their memory
management.
-Non-mouse windows users can interact with Freemem.
When Freemem has the input focus the following function keys work:
(Alt+Tab to shift focus between windows, since Freemem has no caption
bar it is difficult to tell if it does have the focus, see the
Microsoft Windows Users Guide for more info.)
F1 - displays the about box, which contains configuration options.
ALT+F7 - allows you to move Freemem with the keyboard arrow keys, press
enter when done.
ALT+F4 - closes Freemem.
Mouse users:
Freemem can be moved with a click and drag motion.
The right mouse button clicked on Freemem will close it.
A double click on the Freemem window will display the About box containing
configuration options.
Freemem is 'Freeware', no payment is necessary for this application.
Update notes
An option to compute the total of all the free memory fragments has
been added (Bean-Counting). With this method, Freemem has to allocate
each available block of memory in order to determine the total amount
of memory free. This does affect performance, so use the option with
discretion (try to use a larger number of seconds). As a developer, I
find it necessary to monitor memory usage closely and Bean-Counting
provides such a tool.
Note: For Windows 386 users, according to Microsoft there is no direct
way to determine how much conventional memory Windows has available.
Thus, under Windows 386 Bean-Counting is the method used to approximate
the amount of memory free.
Regular method:
The amount of conventional memory free that is displayed is actually
the largest single block of memory free.
Freemem does report the total amount of all the free memory fragments
in the About box (double click on Freemem), as well as total EMS, and
EMS free.
