Can i delete these files


Oct 15, 2011
Hi, my SD card is filling up quite fast, can anybody help me by telling me if I am able to delete some files or if I need to keep them,
If I go into the "File Explorer",then under the "browse" tab it shows various items taking up space on my SD card and a bar display across the bottom of the page showing the size of each of these files.In this bar graph across the bottom it shows I have 3.2 GB taken up by the "misc" file, when I open up the file it is full of smaller files rangeing from a few KB to a few MB.... PLease am i able to delete these files or do I need to keep them or is there some oter way of freeing up my SD card.
thanx, colin
