HxD – Freeware Hex Editor and Disk Editor

Official website: https://mh-nexus.de/en/hxd/

HxD is a carefully designed and fast hex editor which, additionally to raw disk editing and modifying of main memory (RAM), handles files of any size.

The easy to use interface offers features such as searching and replacing, exporting, checksums/digests, insertion of byte patterns, a file shredder, concatenation or splitting of files, statistics and much more.

Editing works like in a text editor with a focus on a simple and task-oriented operation, as such functions were streamlined to hide differences that are purely technical.
For example, drives and memory are presented similar to a file and are shown as a whole, in contrast to a sector/region-limited view that cuts off data which potentially belong together. Drives and memory can be edited the same way as a regular file including support for undo. In addition, memory-sections define a foldable region and inaccessible sections are hidden by default.

ZTreeWin is a fast and flexible text-mode file/directory manager for all versions of Windows.  It has been developed as the successor to the legendary DOS file-manager XTreeGold.  Anyone who has used that remarkable program would be aware of its superior capabilities as a text-mode, tree-structured file-manager – but would also likely be aware that its limited memory support, and lack of long filename support are today a major issue.
ZTreeWin is a native Windows program (both 32-bit and 64-bit) that has been developed to provide all the powerful functionality of the past (and much more!), while avoiding all the limitations of the old DOS-based program.
