Number one is a complete sentence and correct. It may not mean what you think it does, though. Tell us what context you want to use it in.
Number two is not a sentence because it doesn't have a main verb.
Who or what attached the file?Number two is a past tense sentence. It means I attached the file for your reference. The action is finished. What's wrong?
1. Attach the xlsx.file. [STRIKE]for downloading.[/STRIKE] This is an imperative. You are telling someone else to attach the file.
2. I have attached the updated file.exe. [STRIKE]for downloading.[/STRIKE] This is what you would write at the end of an email to which you have attached the file.
See my corrections and comments above.
We can't say which one you need until you tell us the context/situation in which you want to use them.
The one is a statement. ("I attached a file.") The other is an instruction.
1. Attach the xlsx.file for downloading. (This one is an instruction?)The one is a statement. ("I attached a file.") The other is an instruction.
See above. You have to learn how to construct questions.1. Attach the xlsx.file for downloading. (Is this one [STRIKE]is[/STRIKE] an instruction?)
1. Attach the xlsx.file for downloading. (Is this one an instruction?)
When discussing two things it is common to use phrases such as this one and the other one (or the other).
Examples:
We took two dogs to the beach. One got in the water. The other didn't.
Two people were sleeping. One got up. The other hasn't.
I had two loads to wash. One is finished. The other isn't.
Could you mind tell me why you use an instruction?
Would you mind telling me why you use an instruction?
So, the result is
1. Attach the xlsx.file for downloading.
2. I attached the updated file.exe for downloading.
Are they correct now?
