The greatest benefit of portable software is that there are no compatibility issues with various system versions. The packaged application always runs in isolation from the operating system running this application, and has its own registry and file systems for reading and writing data. As a result, portable software can use different versions of the same software on the same computer without affecting the system's registry or file system, ensuring its security and integrity. This way, you can even use untrusted applications without any risk to your system environment.
