No, adding files to a flash drive does not erase existing files. A flash drive has a specific storage capacity, and when you add new files, they are stored alongside existing ones as long as there is enough available space. However, if the drive is full, you may need to delete some files to make room for new ones. Always ensure to safely eject the drive after use to prevent data loss.
Yes.
The Del or Erase command in command prompt.
Do you mean HOW TO ERASE or did they erase by themselves and you want to know why?

By "memory stick", I assume you mean flashdrive. If you want to transport pictures from your computer to your flashdrive, stick your flashdrive into the computer, and open up your pictures. When your flashdrive is in place, another small window should open up with a list of options for you. Among these options should be "open files" or something like that. Click on it, and it will open up any files on the flashdrive (If there is nothing on the flashdrive, there will be words at the top, saying "no files on flashdrive" or "flashdrive is empty" or something like that). Go to your pictures file, and drag any pictures you want from the file to the flashdrive. The End.
Save over files.
Erase
Yes
Please rephrase question. Are you trying to ask how to erase files from your computer? If so, which operating system?
