Usage

wdextract file [-e]

file – filename of VDM container (*.vdm file or MRT.exe executable);
-e optional parameter, extract all found PE image chunks found in VDM after unpacking/decrypting (this including VFS components and emulator VDLLs).

Example:

wdextract c:\wdbase\mpasbase.vdm
wdextract c:\wdbase\mpasbase.vdm -e
wdextract c:\wdbase\mrt.exe
wdextract c:\wdbase\mrt.exe -e

Note: base will be unpacked/decrypted to source directory as %originalname%.extracted (e.g. if original file c:\wdbase\mpasbase.vdm, unpacked will be c:\wdbase\mpasbase.vdm.extracted).

Image chunks will be dumped to created “chunks” directory in the wdextract current directory (e.g. if wdextract run from c:\wdbase it will be c:\wdbase\chunks directory). Output files always overwrite existing.
