FileSieve is currently only available as an installer; a portable version may be released at a later date.
To use FileSieve, you will need to meet or exceed the following minimum requirements.
A Windows operating system that is Windows 7 with at least Service Pack 1 or higher is required. This is an indirect FileSieve requirement; version 4.8 of the Microsoft .NET framework requires at least this version of the OS.
FileSieve has been built on the .NET framework, specifically version 4.8 (click here to download). Please note that the Full version of the framework is required, and not just the Client version that is shipped with some Windows-equipped PCs.
