    @developerNancy Than you'll have to save a reference of the QDir::entryInfoList in a member variable and periotically call QDir::entryInfoList to compare with your member variable List.

    If the latest call contains a file not in your m-Varibale, update your list and upload the new file.

      There is also the QFileSystemWatcher which tells you when there is a change.

      Follow the link given in the post above.

      Vote the answer(s) that helped you to solve your issue(s)

        @developerNancy

        I didn't knwo QFileSystemWatcher was a thing so I'll use that.

        //*.h
        #include <QFileSystemWatcher>
        ...
        
        private slots:
           void uploadViaQNetworkManager(QString filePath){//Your upload code;}
        
           void watcherSlot(QString s);
        
        private:
            QFileSystemWatcher watcher; 
            QList<QString> m_refList;
        
        //*.cpp
        watcher.addPath(PathToUploadFolder);
        QDir dir; 
        dir.setPath(PathToUploadFolder);
        if(!dir.entryList(QDir::Files).isEmpty())
                for(auto &str :dir.entryList(QDir::Files | QDir::NoDotAndDotDot)){
                    m_refList.append( str);
        
        connect(&watcher, &QFileSystemWatcher::directoryChanged, this, &myClass::watcherSlot);
        
        void myClass::watcherSlot(QString s){
           QString newfile;
           QDir dir; 
           dir.setPath(s);
           if(!dir.entryList(QDir::Files).isEmpty())
               for(int i = 0; i < m_refList.size(); i++){
                   bool newEntry = true;;
                   for(newfile : dir.entryList(QDir::Files | QDir::NoDotAndDotDot)){
                       if(m_refList.at(i) == newfile)
                          newEntry = false;
                    if(newEntry){
                       uploadViaQNetworkManager(s+"\n"+newfile);
                       m_refList.append(newfile);
                     }
                }
        }
        

        Disclaimer this is pseudo code and untested. But the prinziple should be valid

        Edit: changed the filter from dirs to files.

          Didn't you say in your first post that you already implemented uploading to the server?

            @jsulm Yes I have done with Uploading Multiple files to server Now I want to implement background sync. like if any file copy in selected folder than it automatically uploaded to server. For this watcher or threading which is the best solution.....

              @developerNancy That I understand. What I don't understand: if you're able to upload multiple files why can't you upload one? So, what exactly is the problem?

                  @developerNancy That I understand. You already was pointed to QFileSystemWatcher, @J-Hilk even provided code. So, what is not working?

                        @developerNancy you don't share any code sample with us, so it's hard to give definite working answers. You'll have to take what we write and integrate into your project.

                        That said I gave you a rough example how to setup and use the watcher.

                        @J.Hilk said in Automatically upload data on server from selected directory path:

                        @developerNancy

                        //*.h
                        QFileSystemWatcher watcher;
                        
                        //*.cpp
                        watcher.addPath(PathToUploadFolder);
                        QDir dir; 
                        dir.setPath(PathToUploadFolder);
                        if(!dir.entryList(QDir::Files).isEmpty())
                                for(auto &str :dir.entryList(QDir::Files | QDir::NoDotAndDotDot)){
                                    m_refList.append( str);
                        
                        connect(&watcher, &QFileSystemWatcher::directoryChanged, this, &myClass::watcherSlot);
                        

                        @developerNancy said in Automatically upload data on server from selected directory path:

                        How I get the Path

                        I don't know! How do you specify the folder for the multi file upload to the server? Just copy that path to a Qstring and give it to your QFileSystemWatcher-Instance
