Welcome to Android File Search project.
The latest version allows now to search files and folders by name. It can be downloaded at https://sourceforge.net/projects/android-file-search/files/Google_Play_Store_Version/
A new version has been uploaded. Filename is "filesearch4.apk". This new version allows to delete files, rename files, delete directories, rename directories, and view text files when the file extension is : txt, xml, htm, html, xsl, xslt, text, ascii, ini, asp, aspx, java, kt, cs, js, jsp, php, bat, css, csv, kml, svg (feel free to ask for more file extensions, that should be a setting in the application in the future). Also, you can force a text read of any file by a long click on a file and then by clicking on "Open as text".
A new version has been uploaded today (10th of September 2019) that now allows to browse the filesystem of the Android device, from the root directory.
New version uploaded. Filename is "filesearch3.apk". This new version now starts browsing from the internal storage of the Android device ("/storage/emulated/0") so you can browse your data file (pictures, alarms, documents, downloads, movies, music, ringtones...). This version also allows you to view the first 1024 bytes of any clicked file in hex format.
No rooted device needed.
I will improve it very soon and will upload newer versions.
