Thanks for your helpful replies Les and others. I've dealt with the directory size issues by using $ du -sch DirName to give a listing for the size of all the subdirectories and files in DirName directory. To split the files under DirName i created 2 subdirs called xxx_DVD-1 xxx_DVD-2 and just moved stuff to each subdirectory using F6 key in mc. Then ran du -sch on each of the DVD-1 and DVD-2 sub dirs. I don't really want to compress things anyway. So that's the file and directory sizes sorted. My only problem now is because some files were created on different OS's, such as Win 32 and possibly Mac OS(X) K3b complains that the character set encoding for the filenames is wrong, and will not create the iso image for me. So I done some Googling and found this posting: International Chars cause backup problems http://forums.fedoraforum.org/archive/index.php/t-98363.html Then I installed convmv and read the docs on that. I'm still not sure how to identify out of 4.3G what character encodings are used for certain files. Is there any way to grep for a listing of these character encodings, so I can tell convmv what sets I want to convert into utf8 please?
