Hi, If you do a ln file1.abc file2.xyz is there a way to erase one and they both go away? Also, it shows that they both are the same size. Is it the case that there is only one instance of the data. If this is not the case, then you might as well do cp file1.abc file2.xyz In addition, which is quicker ln file1.abc file2.xyz or cp file1.abc file2.xyz Thanks, Terry Bailey
