In Google Drive environment, files are identified with a unique ID, which you can read in the URL when you open it for example.
Location and names have no impact with using AppSheet.
You can see that in the Storage section of your table as well:
Data/Table/(pick a table)/Source Id : DocId=1azertyuiopqsdfghhjklwxcvbn123456789
However, if you have some images to redirect, you may want to look into the Section Info/Properties/Default app folder.
