I'm currently trying to find a file sharing and management app that have the following features. So far I had only tried Files Lite because it's the only app that have lite version. Here's a list of features that I want: - Passcode protection for a folder or files. - Built-in image viewer, but with passcode protection. - Fast scrolling/scroll bar display. - Smooth scrolling for large files. - Able to create and edit files. - Able to create new folders. - Able to move files between folders. (Optional) - Landscape support Here's my thought on Files Lite: - Small delay/hiccup when scrolling files (.ppt/.pdf). - Cannot edit and move files. - Cannot create any new files or folders. Questions: 1) Does ReaddleDocs have a built-in image viewer which include image slideshows and multiple transaction as provided by Files. 2) Any app with passcode protection each time I want to open a password protected files or folders? Not the one that only appears once when I launch the app. I think MobileStudio had the ability to create new files but I couldn't find any video reviews on it. So if you have any comments or video reviews link on any one of those app feel free to post here. I wouldn't want to waste over $5.00 for an app that doesn't suits me.
