If you are asking you why to download that utilities/small programs, you need to know that they can be really useful if you work with batch files, or you need some automated tasks. They are virus-free, and for all of them you can see the source, so you ensure that's a clean file.
- Base64: To encode/decode files in Base64. Useful if you want to send files, ensuring that they have been not modified or at least making harder his modification
- BFP (Batch File Packer): As the name indicates, it is for packing (compressing) batch files
- EchoMath: With that utility you can do mathematical operations from CMD directly from
echocommand by piping it. - HexRGBConvert: Convert RGB colors to hexadecimal and vice versa.
- MsgBox: To display customized message boxes, with custom buttons, icons and actions when some action happens
- PlaySound: To play sounds within any window and fast
For batch plugins, I actually use Bat To Exe eVolved. I like it because it is open-source and they cannot be any malware at the code, as we have checked the C code. The other compiler/packer I used before that was Bat to exe Converter by Fatik Kodak (F2KO). I have remove all copies of programs using that because we have found possible malware (rootkits) at the compiled/packed files
For C plugins, I use Tiny C Compiler, by Fabrice Bellard
Why I like it? The answer is really simple: It creates really small executables for small programs (over ~2 kB) and the compiler itself it's also really small.
Yes, all this programs are completely safe as they are published with their source code. To compile you the programs, check up what I use and what to use.
