If it is pointed to a folder look for duplicate file names (prefix) that are not true duplicates, for example if they files have the same name but are different sizes. Then if this occurs alert the user. It would also be very handy if this occurred if the user was provided some sort of tool to rename the files ("You have 10 files that have the same prefix, would you like Drone2Map to rename these so they are not duplicates with the other files in the project?") This was an issue for me when I had both jpg and jpeg file extensions, but the same file name (e.g. file.jpg, file.jpeg). Drone to map allows you to process these at V 2023.1.1, however it gets confused and the output looks wacky. Having this function would allow this not to happen and allow the analyst to resolve the issue.
