Re: [PHP] How many files can be in one directory?
So this means, that I can not increas the amount by splitting the files into more than 1 directory? In fact it would make it even less, because dirs also need those i-nods, right?

This is a parameter when first mke3fs was ran to create the fs. Usually you'll have 1 i-node every 4096 bytes and you need 1 inode per file.

RE: [PHP] How many files can be in one directory?
On a Unix or Unix-like operating systems you should be able to do a df -i to get a report on how many inodes are being used and the number remaining. The output differs slightly from os to os but the base information should be there. Example output from FreeBSD 4.5 follows Filesystem 1K-blocks UsedAvail Capacity iused ifree %iused Mounted on /dev/da1s1a124015392047489034%1348 29882 4% / /dev/da1s1f 1731162 973505 61916561% 76234 35672418% /usr /dev/da1s1e 49583172352838238%2350 1019219% /var /dev/da0s1f711792 316939 32367449% 46523 13158726% /usr/src /dev/da2s1e 3096462 128792 2719954 5%4767 384607 1% /usr/home /dev/da2s1f856770 231188 53990530% 19125 195145 9% /usr/local Jason -Original Message- From: Andy [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 26, 2002 2:32 AM To: [EMAIL PROTECTED] Subject: Re: [PHP] How many files can be in one directory?

RE: [PHP] How many files can be in one directory?
Yes and no. The directory would use an inode, but splitting the stores into separate directories would help drastically improve cpu and memory utilization when working with large numbers of files (10's of thousands) Right or wrong that's what I have to say -Original Message- From: Andy [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 26, 2002 2:32 AM To: [EMAIL PROTECTED] Subject: Re: [PHP] How many files can be in one directory?

[PHP] How many files can be in one directory?
Hi there, I am building a web application which is storing pictures. Is there a limit of files in one directory on LINUX systems? Perhaps it might end in a problem after having 3 files in the same dir? Performance issues ore something else. Has anybody got experiance on that?
