MiniDumper

MiniDumper is a tiny and portable piece of software you can use to examine the structure of files with the help of hexadecimal view. It displays the hex dump of the file's header, which represents the file's first part of 256 bytes.

The program gives you the possibility to copy this data to the Clipboard to paste into a text editor for further processing.

There is no setup file available for this app. Instead, MiniDumper is packed into one .exe file that you can save to the hard drive or on a portable storage device to effortlessly launch it on any PC without setup. It doesn't need DLLs or other components, nor does it update the system registry or generate files or folders on the disk. For uninstall, you just have to delete this executable.

Concerning the interface, the application is as simplistic as possible. It has a single panel that shows three buttons, inviting you to locate and open a file using the built-in file browser or by dropping one from Windows Explorer.

Not only does it show the hexadecimal code of the file, but it also enables you to delete parts of it before copying it. After pasting the Clipboard contents into a word processor, you shall probably notice that, in addition to the hex code, the program displays some details about its maker, along with the file's full path and size.

As we expected, the utility had minimal impact on the workstation's performance in our tests. It was stable in its runtime and ran on newer Windows editions without any compatibility issues, despite that it hasn't received updates for a long time.

In conclusion, MiniDumper delivers a straightforward solution for examining a file's header in hex mode.
