Microsoft+project+portable+1+link

Also, "Link" could be a feature in Microsoft Project. There's a feature called Project Link or Task Link, but I'm not sure. Alternatively, the user might be referring to Microsoft Project Link, which is a different product. Wait, Microsoft Project Link is actually a real product, but it's not widely known. It's part of the Project family but is more for linking tasks across projects. However, I'm not certain about the portable version.
