Short Answer 
To use the Files Marc App, first download it from the Google Play Store and install it. Next, grant the app the necessary file storage permissions, then navigate to your Internal Storage and Android Folder to access your files without restrictions. If problems continue, check for app updates.
Step 1: Download the Files Marc App
Begin by opening the Google Play Store on your phone. Use the search bar to look for “Files Marc Apps,” which features a light blue icon. Once you find it, click on the download button followed by the install option to add the app to your device.
Step 2: Grant Necessary Permissions
After installing the app, open it and allow it access to all the necessary file storage permissions. This step is crucial as it enables the app to effectively manage and display files that are otherwise restricted due to Android’s security limitations. Without these permissions, the app may not function as intended.
Step 3: Navigate to Your Files
With the app open, navigate to your Internal Storage and then to the Android Folder. You should now be able to access and view the contents of this folder without encountering the previous restriction error. If issues persist, consider checking for updates to ensure all your applications are up to date.
