Is there a limit to how many files can exist in a directory?
 

Is there a limit to how many files can exist in a directory? Specifically, on a server running linux/apache?

Can you think of any problem having like 300,000 photo files in a single directory?

yes... only 4 files at a time...

If there is I havent found it. I have one directory on Linux with over 50,000 files in it.

That's good to know.

Only problem I've had with too many files in a directory is with FTP, it's sometimes slow to load up the list.

Yeah, I've had that problem before as well. :(

not sure there is a limit of subdirs in a directory on unix I am not sure what it is its pretyt high though

If you are doing images I would try to put them into sub's. That will make searching easier. And ftp programsa will load faster I think.
