i'm sorry, is that error message not in the source? i'd think it would be possible to change the printf string, or whatever, to
"...: %s", pathname) or whatever. i have many thousands of pathnames piped to it, and i do not know which one is causing it. that is the point of requesting more information. it will take time to do the binary search to find the one that is causing the error. for 64000 files, i will have to run zip about 16 times. please tell me if you want me to do that, or if a grep on the source will find the error message instead. thanks.
