Hi all! I need a little utility and i'm not a programer, so i pray for someone to help me. Basically, it's a delete and rename program. I explain you: I have several version/variants of a program. I want to delete the actual working version, make a copy of the other variant (with other name) and rename it to the correct name for do it work ok. Example: working version -> prog.nds (it´s progA.nds renamed) alternate versions -> progA.nds, progB.nds, progC.nds execute utility -> 1. Select the new version of program to use (version B) 2. Del prog.nds 2. copy and rename progB.nds to prog.nds It's for use several version of some plugins, firmwares, etc. Programs that it's no posible to execute directly. Thanks for all programers that expend his time to read the post and double thanks for the one that answer me.
