You should also be aware that the "original folder" of the SD card is the SD card. If you're looking in Gallery, or some other picture display app, there are a few ways pictures can be displayed - by folder, by date, by name, etc. Pictures are normally in /DCIM/Camera/<some other folder that you create> like "travel pics". But in Gallery, if you have them listed by date, and you took your travel pics and racing events on the same data, they'll all show together, as if they were in the same folder. They're not, they were taken (or moved - it's the last modified date that the date display runs by, and copying is modifying) on the same date.
