Why is the Bluetooth file received by my Nokia C5-03 in the SMS inbox and not in the memory card? How to put it in the memory card?

Many Nokia models are like this. When you open it in the message and then exit, you will be prompted whether to save it, and it will be saved in the memory card. It was previously stored in the memory of the mobile phone (so the size of the received file depends on the memory of your mobile phone). If it is a file in txt format, even if it is stored, it can't be found in file management, because txt is stored in a hidden folder and can only be opened in Notepad (except those with automatic search function). Send downloaded programs, such as SISX, JAR and other files, just change the suffix. In addition, download an X-plore file manager, and you can also find the information transmitted by Bluetooth in your inbox.
