About SD Maid PRO
Although Android has been around for twelve years by now and going through a lot of versions with innovative improvements, it is still not a perfect operating system, just like everything in the world. If you observe your phone closely, you will notice that it runs slower over time. Normally you can reset your phone to the factory state once in a while, but that is time consuming and there is a lot of backing up and restoring involved.
SD Maid PRO was born to eliminate those hassle of maintaining your device’s smoothness. It is a very useful utilities app that packs a lot of necessary system cleanup and optimization tools. With more than ten million downloads on Google Play Store, it is one of the best and most feature-rich system tool apps that support all versions of Android.

What does SD Maid PRO do?
SD Maid PRO consists of many small tools to help you to tidy up your Android devices. All the tools are easy to use, and they all come with explanations in case you are not familiar with the operation of your phone OS. If you are more into manual tweaking, SD Maid also provides tools for advanced users. In most cases where users just do not care, they can simply press on the Scan button to start the inspections, and then hit Run Now and wait for the magic.
CorpseFinder
When you install an app, your system will inspect the app package (the APK file – either downloaded through Google Play or sideloaded from somewhere on the internet) and create some specific folders to extract the package files. Once the installation is finished, you can open the app and your system will access the executable file inside the newly created specific folders to run your desired app. The problem occurs when you no longer need that app and decide to remove it from your phone. The uninstallation procedure involves removing the executable and its associated files, as long as the folder contains them. However, most times the uninstaller cannot detect all the remaining files, so that a large number of unnecessary files remain untouched, taking up your storage space.
SD Maid PRO has a way to solve the problem, and they named it Corpse Finder. The CorpseFinder tools once activated will scan your file system thoroughly, looking specifically for package folders that are not associated to any installed app, and then report its findings to you through a list. Afterward, you can choose to clean everything they found with the press of a button, or go through the list and decide the fate of those residues one by one.
System Cleaner
There are many ways for an app to generate useless files in your phone. For example, it is very common for an app or a game to download video ads to show you while you are using it, and then the video stays in your file system forever even when the ad campaign has ended for a long time. The more ad you see, the more annoying videos you are storing on your devices without even noticing. Some apps need to generate temp files as a part of its algorithms, and they never clean those files afterward.
The System Cleaner feature inside SD Maid is meant to take care of those useless files. When being engaged, they will look for any kind of useless files, such as advertisements, thumbnails, temp files, trash folders, empty directories… and let you decide whether to keep any of them or just wipe them all. You can also set it up to scan for specific file extensions or look in specific folders.
App Cleaner
In addition to generating trash files into your system, apps are usually bad at cleaning their own files too. After a while, your apps’ cache and unextracted data stack up. Cache is always necessary, however when there is too much of it, you need to clean it up or your storage will suffer. Moreover, your storage also suffers from deleted files that are supposed to vanish but instead end up in Recycle bins, downloaded game content that is no longer necessary, bug reports and analytics that apps generated before sending to the developers, etc.
To clean all those files messing around your system, you can choose the App Cleaner feature in SD Maid PRO. Its usage is the same as the two aforementioned features, firstly running a scan and then deciding the fate of those trash one by one or entirely. You can keep the cache for your favorite apps, as sometimes it does help your app to perform better. Browsers’ cache is normally large and it is always okay to wipe them out.
Extra features
SD Maid PRO also provides many interesting features that you might not know you need them. One of the honorable mentions is a file browser that can access the root directory if your device is rooted. If your device is a non-rooted one, you can still browse the SD card and the internal memory files, renaming files and folders, seeing items’ properties, cutting, copying, pasting, etc. These features are basically similar to what ES File Manager can do.
Another useful feature is the Duplicates finder tool. This tool might come in handy when you have downloaded a file multiple times, or having multiple backups of the same contact, etc. While other features might cause confusion by attempting to delete files that you don’t know whether it should be deleted or not, duplicated files are normally just unnecessary and therefore you can press the delete button with confidence.

Summary
SD Maid PRO is a very useful tool for any Android device. Even when flagship phones now can be equipped with half a terabyte of storage and therefore running out of memory is merely a problem, having thousands of junk files and folders does cause phones to slow down as it takes more time to locate an exact file on the system. Keeping your phone tidy and clean is a good habit to maintain its snappiness, responsiveness and reliability.
