Hex Question

[NameTooLong]

You know how when you you open a file with a hex editor it say PK if it's a zip or RAR if it's a rar file? Well what file type starts out with MZ? I think I have a file that's been renamed and I don't know what file type that is.

not sure exactly what you mean. when I open a file with a hex editor, it gives me code, but nothing about file extension or anything.

but anyways file.mz would be a


MZ= Midiprg Mozart compressed file

At the very beginning of a zip in a hex editor it says PK, try it and see what I mean... I want to know what file type has MZ at the beginning and I already knew about the Mozart file by going to Filext and I don't think that's it.

oh you are talking about the pkzip header.

all zip files I have are compressed with winzip and there is no header, but I know what you mean now.

So you are trying to find out what file would have an mz header.

we'll see what we can find, but if the file is small and isn't private or anything, you can send it to me via email so I can have a look see.

I was searching google with

file header; mz

The file in question is 127mb in size and came off a certain site specializing in the field of applications and games (let's just leave it at that). It is named rfs.exe and is supposedly Red Faction for the PC. It has no viruses according to Norton Antivirus 2003 with the latest definitions as of today. I tried running it and nothing happens, not even a flash of a dos window. I renamed it to various archive extensions with no luck. I'm beginning to lose hope so if you don't know, don't worry about it.

I gotcha. I would have done just like you did and tried renaming it to zip or rar etc.

I just ran my own search using the same keywords as you with Copernic Agent Basic and figured out that MZ is found in DOS executables. Problem figured out but unfortunatly not solved.
