Hello I use android file transfer to sideload files from a mac works fine and when I put them either in "downloads" or "DCIM" video player apps find them, recognize the format and play as it should be Problem is when I delete files : They disappear from the list and are no visible anymore from the apps but the corresponding drive space stays occupied It's like if the files are moved in a hidden directory and not really deleted How can I solve this and recover space ?
