Prevent from going back too far

Is it possible to prevent them from going farther back than the specified path folder?  It always seems to let them go as far back as the last folder specified in the root of Controllers/FileManagerController.cs.  For example, if the root folder is z:\\folder1\\folder2\\folder3, and the path specified in initialization is \\folder4, it lets them go back to folder3.  Is there a way to stop them at folder 4?

Thanks for the reply, Keerthana.  The problem is, I am using two instances of the file manager and folder3 is the deepest common folder.  Is there any way I can set the root to folder 4, then go back a folder to folder3 in the path setting for one of them?

let fileObject: FileManager = new FileManager({    ajaxSettings: {      url: hostUrl + "api/FileManager/FileOperations",      getImageUrl: hostUrl + "api/FileManager/GetImage",      uploadUrl: hostUrl + "api/FileManager/Upload",      downloadUrl: hostUrl + "api/FileManager/Download"    },    view: "Details",    beforeSend: function(args) {      var data = JSON.parse(args.ajaxSettings.data);      // Add custom parameter column      data["column"] = true;      // Add custom parameter in ajax settings      args.ajaxSettings.data = JSON.stringify(data);    }  });  fileObject.appendTo("#filemanager");

public object FileOperations([FromBody] FileManagerDirectoryContent1 args)          {              if(args.column)              {                  root = "wwwroot\\Files";              }              else              {                  root = "wwwroot\\Files\\Documents";              }              this.operation.RootFolder(this.basePath + "\\" + this.root);  }  public class FileManagerDirectoryContent1      {          ...          ...          public string TargetPath { get; set; }          public string ParentId { get; set; }          public string FilterId { get; set; }          public string FilterPath { get; set; }          public bool column { get; set; }      }

Thank you, Keerthana,
