Check the configuration of the server. Which Linux distro and version are you using?

Also forgot to ask which FTP server you're using on that server.
</div>


<div>
If I understand what you're saying, trying to have 100,000s of files displaying in an FTP directory listing will likely fail in all sorts of ways.<br />
<br />
FTP just wasn't meant to handle this number of files efficiently.<br />
<br />
Simple solution, no FTP user will be downloading print files, so move these to a different directory.<br />
<br />
Another tip, when purging these files, using <b>find . {args} -delete</b> is far more efficient than any other method. I ended up with some client with... less than intelligent developers, who were dumping small log files in one directory, with no pruning. This resulted in nearly 5,000,000 files which had to be removed. The find -delete trick was the only method that worked, without taking the machine down.<br />
<br />
The solution you mention using, is similar to what I suggest + better to move the temp print files elsewhere, because your solution requires walking the entire directory to match + move files. This can take a huge amount of machine resource + be very slow, for large numbers of files.
</div>


<div>
Let me clarify... Every file in the directory is a temp print file. Depending on the type, some are purged at 24 hrs, some at 7 days, some at 60 days and others 1 yr. The number of files on-hand is directly tied to how busy we are (# of print jobs). <br />
<br />
Users might access at most 10-12 files per week. Unknown which file will be needed until they ask for it, so trying to redirect in advance would not work. <br />
<br />
The FTP client method has been in place for 10 to 12 years with no issues until a few weeks ago. Seems we hit a tipping point.
</div>


<div>
If there's no way to control the number of files (like you said, it's tied to how busy you are), then what if your ftp home directory has 12 folders - one for each month of the year... 01, 02, 03 ... 12 <br />
<br />
Then as each file gets uploaded to FTP, have a script that automatically moves the incoming file into the appropriate folder.<br />
<br />
So at any given moment your home folder has nothing in it except 12 folders.<br />
Basically you're dividing your files into folders so you don't overload the FTP server and the linux os.<br />
<br />
I'm sure a linux guru could help with the script.<br />
Or look to the FTP server software to do it. For example, check out crush<a href="ftp://ftp.com" rel="ugc">ftp.com</a> &nbsp;It has a lot of automation options.

Thanks, <br />
I am unable to modify the directories without involving the Software company. And I will likely reccomend such changes for a future release. In the interim, I am stuck with what I have. <br />
<br />
I agree that the issue is on the client side FTP program unable to handle so many files. <br />
Playing around with Filezilla, I found that although the file may not be listed, the search function finds it no problem. I will simply show the users to use search instead of of scrolling through the files (which is more efficient anyways). \
</div>


<div>
congratulation! The work around solution is cool.<br />
<br />
Anyway, Keep a directories structure needn't involving the software company.<br />
You just need a periodic run script which scan the files and move then to sub direcotries by some rules.

Experts, <br />
I have an application on a linux server that writes some output files into a single directory. With recent growth in business that directory has about 147,000 files in it at any time. &nbsp;These are mostly temp print files that are continually purged <br />
<br />
I have a handful of users that use FTP clients (WS_FTP and Filezilla) to copy specific files from linux to their PC's. This is not working anymore, the FTP clients are only displaying a fraction of the total files. <br />
<br />
I am not sure what is going on. Is there a limitation on either the FTP client of Linux server? Is some type of network or firewall issue preventing listing of all files? Is the issue at the desktop level? <br />
<br />
As a temp solution, I am forced to access the Linux server and copy the file into a new (near empty) directory. The user can then grab the file from there no problem.

FTP from LINUX. Too many files?

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

The File Transfer Program (FTP) is a standard network protocol used to transfer computer files between a client and server on a computer network. Built on a client-server model architecture, it separates control and data connections between the client and the server. Users may access the server through a sign-in protocol, typically in the form of a username and password.

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
