One of the more mundane aspects of modding and theming an Android device is probably the testing phase. Consisting of either constantly creating and flashing test ZIPs through a custom recovery, or going back and forth copying and pasting files, a good file manager can definitely be of great help. In addition to this, manually setting the correct permissions for each file is just another chore modders and themers have to deal with.
But even if you are content with your current file manager app, it may still be an idea to give Sysfile Copymaster a go. Developed by XDA Senior Member Flextrick, Sysfile Copymaster is not your ordinary file manager. Rather, it’s a dedicated app especially for modders and themers and the boring things they must do.
How so? Well first of all, it’s user interface consists of two sliding panels, one called the ‘System section’ that displays all the files of a /system directory, while the other called the ‘Storage section’ displays the files of a predetermined directory in your storage. If you want to copy certain apps and files from the root directories to storage, simply select them and press the ‘Copy to storage’ button, and the files will be copied to the predetermined storage directory. Similarly, if you want to copy files from your storage directory, just select them in the ‘Storage section’ and press the copy button, and the apps will be copied to the specified root directory with all the correct permissions set. By doing this, Sysfile Copymaster cuts out the navigation, the copying and pasting, and the permissions aspects by doing them all automatically.
Flextrick has designed a very simple and straightforward file manager that many modders and themers will definitely find useful albeit not your conventional file manager. It’s compatible with devices running Android 4.0 and newer, and can be downloaded for free from the original post.
