8.4.2 Memory dump file copy command (mdump)
<Name>
mdump - Copying a memory dump file
<Syntax>
mdump [-n | -e file name] <Copy (Decompress) destination path name>
<Feature>
The mdump command compresses a memory dump file collected by Microsoft® Windows®
when the equipment stops unexpectedly. Then the command copies the compressed memory
dump file to a portable medium. The dump file, which is specified in the Startup and
Recovery window displayed by selecting Control Panel > System and Security > System >
Advanced system settings and clicking Settings under Startup and Recovery, and all the
files under the minimum dump directory will be saved. The memory dump file is compressed
and stored as a file (File name: MEMORY.zip).
As an option, if you use the -e option, the compressed file will be decompressed.
The following options are available for this command:
-n: Files will be copied without compression.
-e file name: A file compressed by the mdump command will be decompressed. You must
specify the file name.
Copy destination path name: When the -e option is not specified, specify the drive name of
the copy destination. If you want to copy files to a directory, specify a full path
including the directory name.
When the -e option is used, specify the directory where you want to store the
decompressed files.
・A memory dump file is copied to the copy (decompress) destination specified by this
command.
・If a file with the same name as the copy (decompress) destination already exists at the
same location, the file is overwritten.
・When you run the mdump command by typing “mdump /?” or “mdump -?” at the
command prompt or when there is an error in the specified parameters, a help message will
be displayed to show how to use the command.
