I could not get Astro to work, so I went w/ Estrongs F/E. This works great! Done a scan, found my desk top, viewed all files and folders that I wanted to...BUT cannot open any document. Word, Excel, PDF, MP3, etc. Everytime I click on the files it says "Sorry, No Application Installed." I can open these types of files if they are attached to an email, but not in Es File Explorer... Anyone have any suggestions??
