Hi Sudip - to clarify, do you want to know what extension to use to check for a folder in the list of Dropbox contents? What code are you using to get the list from Dropbox?
Folders do not have extensions, but I don't think looking for 'nil' is what you want. You can check if an entry is a folder, not a file, but looking at the type of metadata returned by the call to listFolder, and checking if it's FileMetadata or FolderMetadata. See the "Upload a File" section of the iOS tutorial here: https://www.dropbox.com/developers/documentation/swift#tutorial
