Hi clairemissy,
Thanks for the post. I understand you have a question about a folder being created in Image Capture.
It sounds like you may want to double-check your import settings. To do this, open Image Capture with your device connected, and then click your device name in the left column. Then, look for the "Import To" drop-down menu at the bottom. There, make sure you've selected the correct folder for importing, and also that the "Make subfolders per camera" option is unchecked.
I hope this helps! This has more Image Capture information for your reference: Transfer images in Image Capture on Mac
Take care.
