DumpPE Version 1.23
Clive Turvey's freeware utility for dumping the header information of Portable Executable files with the option of dis-assembling the file into a text file. Version 1.23 is a 32 bit console mode application which will now dis-assemble KNI (Katmai New Instructions) and 3DNow! instructions. This is a very useful tool for programmers who are writing PE type executables or DLLs as it displays the import and export tables which is useful in making DLL calls.

Programmer's File Editor
This is the last release of Alan Phillip's excellent large capacity Programmers File Editor. Alan's site now advises that PFE will no longer be developed and the site is now closed to downloads. It has the capacity to open very large files up to the memory limit of your computer. It is a highly configurable, very stable and has more options that you can learn to use in a lifetime. This is one of the few programs that will load very large assembler dumps without problems
