Whats the safe maximum for a Winzip file?

Hi

I need to save a whole load of data to DVD but as there are so many folder
depths I cant just copy to Nero as it contravenes Joliet and wants to
truncate filenames etc which is a pain.

So I thought I get over this by using winzip to compress specific folders.
But I'm not sure about the maximum number of files or total data size that a
winzip file can safely compress.

Thanks for any info.

Ian
PS is there another way to get around the problem of deep levels of folders
when saving to DVD via Nero?
 
Don't even bother with ISO/joliet when burning CD/DVD today.
UDF 1.02 has been supported for 7 years. Long names and unicode.

Here are the lomits for the free zip from info-zip:

It also contains comments for pkzip. Not sure what happen with
regard to winzip, but it has probably the same limitations.

Or the entire folder tree. That works fine.

There isnt any practical limit with DVD sized zip files.

Nar, that's about the best approach. UDF format for the
DVD is another possibility, but its got some differences
on what it can handle, so isnt so completely bulletproof.
 
Ian,

Modern ZIP tools (like WinZIP or JustZIPit) use ZIP-64 format which
does not have any "practical" limits. The only ZIP-16 format did have
substantial filesize, and filecount limitations.

UDF's heavy reliance on the TOC make some view it as insufficiently
reliable for frequent write/rewrite scenarios or tasks of great
importance like backup. It's not a pretty thing when the TOC is
borked (through user or media failure). That may steer some to other
formats or media despite UDF's ease-of-use convenience.

The OP is writing DVD-R, and the TOC is irrelevant to UDF vs ISO.

Seems relevant to me when in one instance the TOC is written once and
you know whether the disk was recorded successfully on the onset - as
opposed to every change to a live filesystem causing an update to a
single physical region which when corrupted or erased requires special
HW to recover the data it served to locate.
