“After downloaded” vs. “After downloading” [closed]

Question

What is the difference between "After downloaded" and "After downloading"? Are they both grammatical?

After downloaded, I start running this program.

After downloading, I start running this program.

Is it also correct to say "after to download"?

"After downloaded" and "after to download" are ungrammatical. As any native speaker or any good grammar book will tell you. After is a preposition, as any dictionary will tell you. It thus can precede a gerund, which functions as a noun, but not a full infinitive or a simple-past form. This question is too basic for this site.

In addition to what myselfpoddar has said, the first sentence can also be expressed as "After having downloaded (the file).

The last option (after to download) is totally ungrammatical because you cannot use the infinitive after a preposition.

	@JammyC.c As far as I know, you can find the first in written texts but you rarely use it in speaking; however, the meaning of the two expressions is equivalent. – Paola May 13 '12 at 8:13
