public override FileManagerFilePermissions GetFilePermissions(FileManagerFile file) {
    int fileId = int.Parse(file.Id);
    Permissions permissions = Data.PermissionsSet.FirstOrDefault(p => p.Item.Id == fileId);
    if(permissions == null)
        return FileManagerFilePermissions.Default;
    return GetFilePermissionsInternal(permissions);
}

public override FileManagerFolderPermissions GetFolderPermissions(FileManagerFolder folder) {
    if(string.IsNullOrEmpty(folder.RelativeName))
        return FileManagerFolderPermissions.Default;
    int folderId = int.Parse(folder.Id);
    Permissions permissions = Data.PermissionsSet.FirstOrDefault(p => p.Item.Id == folderId);
    if(permissions == null)
        return FileManagerFolderPermissions.Default;
    return GetFolderPermissionsInternal(permissions);
}
