Anyone know if there's a hard limit for FTP url/file paths and, if so, what it
is?

Cheers

If you're talking about a URL, none that I've been able to find. Same goes for the FTP RFC. So, no, probably not, except if your OS defines an upper limit on path names.

Thanks to you all for your prompt answers.

Here's an interesting twist. The doc for FtpGetCurrentDirectory() says

    "Using a length of MAX_PATH is sufficient for all paths."

Looking at the question again for Internet Explorer its actually a maximum
URL length of 2083 and a maximum path length of 2048.
As far as I know there is no specified limit and some other products have
different length.

The hard limit is when your stack buffer overflows and a virus gets written onto it.

Yes, very good. ;)

In fact, I've fixed up various assumptions of path length in STLSoft and recls,
and there are now the classes basic_file_path_buffer in both WinSTL and UNIXSTL,
which provide the appropriate sized buffers. For WinSTL, if the OS is NT, then
it
provides a buffer of 32001, 9x it provides 261. For UNIXSTL, if PATH_MAX is
defined, then the length is 1 + PATH_MAX, otherwise it calls pathconf().

For InetSTL it's not assuming any length at all for most of the code, although
things that deal with FTP directory lengths do assume _MAX_PATH, since that's
documented in the WinInet API.

btw, the next version of recls, which I'm working on right now, will allow FTP
searches on Win32. (I'm using ftp.digitaldaemon.com as my test site <g>) I'll
naturally be updating the D mapping.

The best approach is to do one's damdest in writing the code to avoid any
need to even know the maximum path length.
