copy - strange behaviour at files bigger than 4 GB #108

I tested the copy command and found a strange effect: In Win and in Linux files cannot be copied on FAT32 when they are bigger than 4 GB. There is an error message that prevents this. So far ok. In FreeDOS I tested the copy command with 3 files, 1,6 GB each, the files contain only "AAAA...." or "BBBB..." or "CCCC...". I ran: copy filea.txt + fileb.txt + filec.txt filenew.txt (alltogether 3 x 1,6 = 4,8GB). It runs through, there is NO error message, but the result is as follows: filenew.txt contains the following text: 0,8 GB "C" at the beginning followed by 0,8 GB "A" then 1,6 GB "B" and 0,8 GB "C". This means: it simply starts with the text that cannot be written at the beginning. Not a big problem, but an unusual behaviour.
