special character [moved]

i have faced recently a very big problem with the file manager on cpanel

i have uploader a file (Cv2006+someworks.pdf) and i can uploaded it Succesufly and i cloud download it from http and ftp succesufly also
and when i finished with the file and want to delete it, move it or even rename it

because the cpanel system cant Recognize the (+) plus sign in the file name and replace it with a space, thats mean i get a message from cpanel that there is no such file name called (cv2006 somworks.pdf) and it reserve a big diskspac e quota fo no need.

please help how can i solve that problem
