With naBoota update 1.4 and Convertset update 1.0.9, both programs have native 64-bit support.
naBoota and Convertset will now check if your system is 32-bit or 64-bit before starting a process, and afterwards run the corresponding 7zip or FFmpeg process.
64-bit support means the process will be faster on 64-bit systems, which is nearly all computers today. Until these versions, both naBoota and Convertset used 32 bit processes to do their jobs, which meant they would run on both 32-bit and 64-bit systems. However, native 64-bit programs are more efficient and can use more system resources than native 32-bit programs. Now, 64-bit systems can have their well deserved upper hand.
After these updates you might also notice faster startup times as well when you run either of these programs. (This is not related to the 64-bit support.)
