Note: It may be hidden so will need to enable 'view hidden files' to see it.

In addition, you may not be able to save it unless you have opened it as an administrator. Take look at this article for a guide.

Does "It may be hidden so will need to enable 'view hidden files' to see it" mean "It may be hidden so that we will need to enable 'view hidden files' to see it"?

If so, what grammar did these sentences (verb + so + verb pattern) apply to? Is it possible to convert the verb + so + verb (be hidden so will need) pattern into a pattern with the subject and verb we are familiar with?

Is the verb + so + verb pattern without a subject grammatically correct?

Answer 1

I'm pretty sure this is actually a typo. That clause needs a subject and it doesn't have one. Sometimes you might be able to get away with not directly stating the subject. This is not one of those times.

Presumably, there's a "you" (assuming this is instructions) right before the will. It could also be "we" as you guessed if he assumes you're following along and doing exactly the same things as him.
