...what is Microsoft Visual C ++ and why do I have so many files?
Some programs are extremely picky about which version of the Visual C++ programming language they use. Programmers are supposed to add in some code to allow the program they write to figure out that a later version of Visual C++ will work right, but they are notoriously lazy and often incompetent and neglect to do so.
(The last part is a joke. I just finished a semesters worth of C# programming.)
Anyway, Windows keeps the various versions around "just in case". I have sixteen different versions on my main computer, though since I've had to do some programming of my own that is more than I would expect for most people.
Unless you are sure you don't need one, I would leave them alone.
How many bites are a really large file?
Large is relative.
[gratuitous sexist joke goes here] :devil:
1 terabyte = 1,000 gigabytes
1 gigabyte = 1,000 megabytes
1 megabyte = 1,000 kilobytes
1 kilobyte = 1,000 bytes
1 bite = getting tossed out of the Garden of Eden
(There are slightly different ways of measuring this, but this is the least confusing and works fine for your question.)
Personally, until a file gets above 50MB I don't worry about it. I do follow what WHS suggested about cleaning out the crapola with CCleaner.
