ERROR :The specified path, file name, or both are too long.

[Ajay]

Hi telerik Guys !

Im using RAD FILE EXPLORER as the main control in my current project.

Actually what Iam here trying is to create a nested ROOT structure just like :-

----Root
        :
        : -------Child Folder 1
                    :
                    :---------Child Folder 1a
                                :
                                :---------Child Folder 1a(i)
                                            :
                                            :--------Child Folder 1a[i(a)]
                                
Now when I try to UPLOAD an file within the Child Folder 1a[i(a)] folder Im getting the below mentioned error  in my CustomFileSystemProvider.cs class:-

"The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters."

Below is the code that is creating an problem :-

 public override DirectoryItem ResolveRootDirectoryAsTree(string path)
    {
        string physicalPath;
        string virtualPath = string.Empty;

        if (this.IsPhysicalPath(path))
        {// The path is a physical path ;
            physicalPath = path;

            foreach (KeyValuePair<string, string> mappedPath in MappedPaths)
            {
                // Check whether a mapping exists for the current physical paths ;
                if (GMP.AddSlashAtEndOfPhysicalPath(physicalPath).ToLower().StartsWith(mappedPath.Value.ToLower()))
                {// Exists
                    virtualPath = Regex.Replace(GMP.AddSlashAtEndOfPhysicalPath(physicalPath), Regex.Escape(mappedPath.Value), mappedPath.Key, RegexOptions.IgnoreCase);
                    virtualPathvirtualPath = virtualPath.Replace('\\', '/');
                    virtualPath = GMP.AddSlashAtEndOfVirtualPath(virtualPath);
                    break;// Exit the 'foreach' loop ;
                }
            }

            // Mappind does not exist ;
        }
        else
        {// Virtual path ;
            virtualPath = GMP.AddSlashAtEndOfVirtualPath(path);
            physicalPath = this.GetPhysicalFromVirtualPath(path);
            if (physicalPath == null)
                return null;
        }

        DirectoryItem result = new DirectoryItem(this.GetDirectoryName(physicalPath), string.Empty, virtualPath, string.Empty, fullPermissions, null, GetDirectories(virtualPath));

        foreach (DirectoryItem dirItem in result.Directories)
        {
            // Get the information from the physical directory
            DirectoryInfo dInfo = new DirectoryInfo(Context.Server.MapPath(VirtualPathUtility.AppendTrailingSlash(dirItem.Path)));

            // Add the information to the attributes collection of the item. It will be automatically picked up by the FileExplorer
            // If the name attribute matches the unique name of a grid column
            DataTable dt = new DataTable();
            dt = Glb_Entities.ExecuteSPReturnDT(new object[]{"Usp_Dms_FolderDate"
                                                             ,"Folder_Path", (dirItem.Path.TrimEnd("/".ToCharArray())).Substring(0,dirItem.Path.TrimEnd("/".ToCharArray()).LastIndexOf("/"))
                                                             ,"Folder_Name", dInfo.Name
                                                               });

            dirItem.Attributes.Add("CreatedDate", dt.Rows[0]["CreateDate"].ToString());
            dirItem.Attributes.Add("ModifiedDate", dt.Rows[0]["LatestDate"].ToString());

        }
        return result;
    }

Problem exist in the italized text in the above code.

Hi, today I also faced this error when trying to use upgrade wizard on reports, which I did a few times the past week without a problem. After searching for hours to find a solution, I checked the file name/path lengths. Since I did not delete the old backups that the wizard makes and I use the solution's directory to make the backup, each time it includes the previous backup directories in the new backup which results in 254+ lengths - 
C:\dir\dir\dit\Backup5\dir\Backup4\dir\Backup3\dir\Backup2\dir\Backup1\dir\Backup\dir\Report.cs 254

Deleting the old backups solved my problem.
