Why does the sentence use 下载了以后 instead of just 下载以后?

下载了以后 is a very common pattern in Chinese:

• Verb + 了 + 以后 = after doing something
• so 下载了以后 means after downloading

The 了 shows that the downloading action is completed before the next action happens. In everyday speech, some people may omit 了 in certain contexts, but 下载了以后 sounds very natural and clear here.

So the timeline is:

1. download
2. then save the file properly

What exactly does 以后 mean here?

Here, 以后 means after or afterwards.

In this sentence, it follows a verb phrase:

• 下载了以后 = after downloading

Chinese often builds time relationships this way:

• 吃了以后 = after eating
• 下课以后 = after class
• 看完以后 = after finishing reading/watching

So 以后 helps turn the first part into a time clause for the main instruction that follows.
