Hidden files
 

what should do? Or how to delete that I have 2 hidden in my PC?
I know nothing that's why please tell me detail if some one know about it?

More information would be useful, but a hidden file on a posix filesystem is merely one with a . at the start of the file name. so "rm .filenamehere" would delete it.

Are you perhaps using a graphical user interface like Ubuntu? If so, you may need to resort to the command line.

Ctrl-H in Ubuntu or Ctrl-. in Kubuntu default file browser will show hidden files. You will be able to delete them.

If the files are owned by root, you can go to the command line and sudo to rm ("remove") the files or, if you want to use a graphical file manager, start Konqueror or Dolphin from the command line with root privileges with sudo konqueror or sudo dolphin (don't be alarmed if you see some error messages in the terminal before the program starts).

it is useless to speculate ,until "WilliamTN" posts back with MORE info
the only thing we know is
there are two hidden files on some UNNAMED operating system
the op has a windows flag so this might be a MS Windows question ????

we do not have enough information
