Bits is small standalone Windows utility that checks if a PE file (for example an .exe or .dll) is 32 or 64-bit from an Explorer right-click menu.
Bits is composed of a single file (Bits.exe). Unzip the downloaded zip file and place the "Bits.exe" file within it wherever you like. To install/uninstall the Explorer context menu simply run the program and follow the prompts.
Right click on the file and choose “32 or 64-bit?” from the context menu.
Bits is designed to be as small as possible, to have as few dependencies as possible and consist of a single file. It would be nice if it’s useful too. Another goal is for the code to be a guide on how to create apps in C/C++ with these constraints.
