Text Cleaner For Spaces ?

I have some HUGE text files (easily around 2000+ lines) I need to clean where some of the formatting is like this:

CODE:

Of course there are more than 2 words in the lines, but what I said was just an example. I have to clean these files and I just want to know how to delete the whole line after the spaces (including the gibberish), but I don't want to delete the spaces in between the words that need to stay.

I was thinking I could test for 2 or more spaces and if that's true then delete the rest of the line beginning at the first space. The only issue is there are tabs sometimes between the words and I don't want to mess with those right now. (I have no clue how to make source that deletes spaces but not tabs... Perhaps you can single out tabs?)

Because of the formatting to make the text files look "cleaner" there are sometimes 5 (least) - 8 spaces (max) between each some words. So should I check for 9 spaces? (1 more than 8). There seriously are huge amounts of spaces between the words and the gibberish.

I'll worry about formatting the text and what not later, right now I'm only asking for help with the spaces and gibberish issue .

I'm usually a C++ man, not used to VB.NET (2005) but I will only be using this project for cleaning these files and the dialogs are much easier to make than MFC for C++. So I figured this would be much faster and easier (except I have very little experience with VB.NET)
