deleting core file??

hi,

i am using unix through exceed on my pc to gain access to some cfd programs. one of these programs crashed a couple of days ago and created a file called core, which i understand is a back up file and can be deleted immediately. however, before deleting it i rearranged some of my other files in my area, then tried to delete core. however, it would not delete and then all my other programs would not open correctly or load files. any advice?

thanks

a core file is not a backup file. it contains a snapshot of the program state at the time of the error. it is safe to delete a core file, however, rearranging any files before doing so shouldn't make any difference. it is most likely a permissions issue.
if you are want it removed, you can ask your admin who will have the necessary permissions to do so.
