Fdocuments -

FDocuments gets the absolute basics right—it opens quickly and reads PDFs without lag. However, it lacks the advanced features and polished interface of competitors like Google Drive, Solid Explorer, or even Microsoft Lens.

Since "FDocuments" can refer to a few different generic utility apps (depending on your OS), this review assumes it is the commonly available for Android. Review: FDocuments – Lightweight but Limited Rating: ⭐⭐⭐☆☆ (3/5) fdocuments
