Charlie is correct about the OS itself. However, several file manager apps (such as Resco) add a recycle bin for files deleted using that file manager. And while there is generally no benefit from defragging RAM storage, defragging memory cards on a regular basis can keep access time from degrading to some extent. I have found the quickest way to defrag a memory card is put it into a PC's card reader, copy all contents to the PC, format the card, then copy the contents back to the card. Device-based defrag apps work but are very slow. |
