see windows hidden files with knoppix

Or if you willing to use command lines to perform the copying, you can use the cp command together with the wild card characters ("*").

For example, on the directory /photo you have 50 files on it, 30 of them are files containing accent characters on the file name but with the extension .jpg. And you want to copy these 30 files to your external drive mount at /media/sda1

So all you have to do is to issue the command

$ cp  /photo/*.jpg  /media/sda1

Or just copy the whole directory content to the external drive

$ cp  /photo/*  /media/sda1

Then handle all the copied files on another windows box with the external drive plug in.
