I've just replied to another user who had issues with Hacha.
It's not hard to use - I think the biggest problem with it is the language. Second, it requires some computer literacy, but you can learn a smattering of both - spanish and computer - easily.
So, here's my quick help.
First, execute Hacha. Be sure you got at least version 2.98. If not, look for a newer version on TT or through google.
When loaded, you'll see a menu with a drawing on the left, an axeman, and two icons on the right. Cortar means "split", Pegar "join". The icons are self-explanatory, though.
To rejoin an archive just extract all files from the downloaded zips. To properly open them, use winzip, from
www.winzip.com.
Now select Pegar - Join - on the menu, look for the extracted files, and point to the .0 file.
[You got at least two files, with .0, .1, .2, etc. extentions. Just look for the first of them, "yourfile.avi.0", or "whatever the name.0"]
The next menu has three options: Origen=Destino, Borrar Fuentes, Check CRC.
You can leave the first selected - it means Hacha will rejoin the file into the same folder the split parts rest.
Borrar fuentes means Delete Source. That is, if you are familiar with Hacha, you can instruct it to delete the split parts.
Check CRC just means check if the rejoined file is identical to the original one. Doesn't matter since few use it to split files, so leave it unchecked.
If you don't select Origen=Destino, select an output folder, and let Hacha join the parts.
Just close Hacha, and look for your new, rejoined file.
Keep in mind there a couple of versions out there, so be sure to ask what version a particular file has been split with.
This doesn't cover everything about Hacha, but at least now you know what the menus mean.
