Generally, phone internal memory is limited. Most Android users insert a SD card into their phone for more storage space so that they can install applications and store backup files. Nonetheless, this will accompany problems. If you do not clear or wipe the cache files in time, it will occupy most room of the SD card. For your convenience, we have systematically sorted out all kinds of folders in the SD card.
