A benchmark wouldn't be accurate, as it will be IO bound, and being an old
machine, better reduce disk IO than CPU usage (I'm guessing it uses IDE
drives; which have low access time too). Besides, first option can fail if
you don't have write access to the file, thus needing a third access to
check for permission to delete. Better use Try and catch the Error; let me
explain:

If you want to analyze the access to disk, the Try/Catch will access n
times the disk, n the amount of files. The <If Exist(...) Then Kill ...>
will access the disk at least n and at most 2n. 3n at most if you check for
write permissions.

Anyway, that's my opinion ;)
