Client list files completion handler
Hi,
I am successfully listing the contents of a Dropbox folder, however I was wondering whether there is a way to call a completion handler when all the files have been listed?

- Thanks! In this case, you'd want to run your desired code when the listFolder or listFolderContinue response has hasMore=false. The hasMore value tells you whether or not there are currently any more results to retrieve. If it's false, you know that you've received the entire listing.
You're already using hasMore to control whether not to call back to listFolderContinue again, so you can expand on that to run some other code when that's done.

Can you let me know which SDK you're using (if any) and share the code you have so far so I can offer some specific guidance? Thanks in advance! Hi,
I am using the Swift Version.
Essentially, I am listing the contents of a directory on Dropbox, and filtering for a specific type (which in my case is PNG).
Basically what I need to know, is whether there is a way of being notifiied when the listing of the files has been completed?
Any help would be great :)
func listRemotelySavedFiles(validType:String){ //1. List The Files If Any if let client = DropboxClientsManager.authorizedClient { client.files.listFolder(path: storageVault, recursive: true, includeMediaInfo: true, includeDeleted: false, includeHasExplicitSharedMembers: false).response(queue: DispatchQueue(label: "Tests"), completionHandler: { (response, error) in if let result = response { for entry in result.entries { if let details = entry as? Files.FileMetadata{ let entryName = entry.name as NSString let pathExtension = entryName.pathExtension // Only Make Reference To Valid File Types if pathExtension == validType { self.dropBoxDataVault[entry.name] = [entry.pathLower!, details.contentHash!] print("Unique Hash For Remote File \(entryName) == \(details.contentHash!)") } } print("Completed *________*") } //If The User Folder Is Very Big We Need To Call List Continue & Continue To Extract The Data From The Remote Files repeat { client.files.listFolderContinue(cursor: result.cursor).response(completionHandler: { (response, error) in self.remoteFileCount = result.entries.count if let result = response { for entry in result.entries { let entryName = entry.name as NSString let pathExtension = entryName.pathExtension // Only Make Reference To Valid File Types if pathExtension == validType { self.dropBoxDataVault[entry.name] = [entry.pathLower!, self.generateRemoteHashTagForFile(path: entry.pathLower!)] } } }else{ print("An Error Occured Continuing To List The Folder") } }) } while result.hasMore == true } else { print("Error Loading Files") } } )} }- Greg-DBThanks!

Can you share the final working code to list all the items in a folder. I have a folder where there are more then 5000 folders.
Thanks,
