I'm sorry but I'm a little bit confused at the "drag with the cetsor the file save01 and leave it onto the app" where can I find the "Save01" file?
When you make a save into the game this save becomes a file named Save01. If you make four saves for example the files will be: Save01, Save02 etc and these files appear right below of the Quick_Save file (where it says Pocket Mirror. exe, right below there are the files: Pocket Mirror.ini, Pocket Mirror.rgss3a, Quick_Save. Right after Quick_Save the files Save01 etc take place) If you haven't saved the game there will be no file.
