For those of you who still dislike using HJSplit or FSJ then there is another way of both uploading and downloading larger clip that you might find easier to use:
WinRar
This can be used to download and upload .rar files in here and I have noticed that there are one or two around and in case this catches on, this is a quick "How To" to download and join .rar files.
First, download winrar, (google it, it is free) and install it on your pc (ensuring that the "shell integration" boxes are ticked, see pic below)
Secondly, As you would normally do, download all the .rar files that make up your particular clip and ensure they are all in the same folder on your pc
Thirdly, right click on the first .rar file and in the drop down box under winrar chose the option "extract here"
Lastly, let it do its stuff, (no need to click on any other .rar file as the program will recognise that the other .rar files are present and will extract them without any input from you), once it finishes you will find the complete film joined ready to watch.
It really is as simple as that guys!!
