Hello!

I will cite a few examples for you:

When I was younger, I have seen many physical products with series of lines and spaces on them.

This is a bad sentence, as there is no need to use Present Perfect here. This tense is used to indicate a link between the present and the past, and particularly in cases where we are more interested in the result than in the action itself.

This sentence should read: "When I was younger, I remember seeing many physical products with series of lines and spaces on them."

Many months later, after severally questions of what those lines and spaces are, I was told it's a Barcode, and the device I saw on the television was its scanner.

I've said it before and I'll say it again: long sentences make the text hard to read. It is hard to communicate your message effectively to the reader in a lengthy sentence without careful crafting.

This sentence should read: "Many months later, after several questions about those lines and spaces, I was told it was a Barcode, and the device I had seen on television was its scanner."

The paragraph above simply means, BinaryEye lacks the ability to open other types of contents

This would be a better sentence: "The paragraph above simply means that BinaryEye lacks the ability to load/process other types of content"

I hope you will find this comment useful.
