PeaUtils is a free, open-source file management suite derived from PeaZip, offering portable software that doesn't require installation. Supports file hashing, checksum, secure deletion, file splitting, and joining, and is free for any use under the LGPLv3 license.

Using PeaUtils is easy. Simply open the application by clicking on the program's shortcut or on the pea.exe file located in the program's folder. You can drag one or more files or folders onto the program, or use its standard open file dialog. After that, just select the function you want to perform on the listed items, and you're good to go.
During setup, the Windows installable version also offers an alternative option. It can create a submenu in the system's context menu that provides quick access to a customizable list of the most commonly used file management tools, such as the eraser and integrity checker.
PeaUtils is an open-source program that is free for both private and professional use. It is based on the PeaZip project and is intended to provide a simple and user-friendly GUI that makes it easy to access file management functions. The program is available for Microsoft Windows and Linux systems, and it is also available as portable software that does not require installation. This feature proves to be extremely useful when deploying the full set of functions to a host machine, which cannot allow for software installation modifications.
