Recently I uploaded a audiobook in which only 5 of the 20 chapters would work. Every chapter has a -rw-r-r code. In a terminal, it acknowledges I am the owner but it refuses to allow me to delete the files. I have tried everything I can but to no avail. The files exist on my mp3 player and I am just trying to take them off. I am new to linux and have spent hours going through all the information from people who know and it still cannot do what i need it to do. Please Help.
