"Can't concat same file types-concats prev splits?"
Don't know as I was not interested in splitting a file.
Don't know as I was not interested in re-combining a previously split file. The description is misleading as it says "MacHacha is a utility to split and join files" when it should say "re-combine" or "re-join" files that have been previously split by a utility and have x.y.001/2/3 formats?
I tried joining 3 files: MOV00011.mpg, MOV00012.mpg, MOV00013.mpg and got a flash msg so fast that I could not read it. I converted my files to mp4 and tried again with same result. I spent time looking up descriptions of this tool and realized that it re-joins file that you have already split using this utility or a similar utility.
It needs to explain by adding sample before and after file names. For wasting my time, I gave it 2 stars although when used as intended it may perform extremely well.
