Thanks to WiFi, sending documents will be done without having to connect any cable, including the standard USB. Searching by folders is more tedious, especially when it comes to doing it because of the different ones that the Android directory shows, which can be almost infinite.
Creating a WiFi hotspot

When sharing data, the user can create a WiFi access point, thus having the ease of transferring files from the mobile to the PC through the wireless signal. This point will allow the two devices to see each other, all without the need to use the charging cable that comes with the terminal.
The method works as long as both have a WiFi connection, both the phone (they all have it) and the PC. If you don't have the second, it's best to get a WiFi USB. The peripheral is quite affordable, which can vary but will not cost more than 12-15 euros, all depending on the brand.
