Hi Sheik,
I believe it has got something to do with pre-requisites. May be you need to edit the "hard nofile" parameters in /etc/securuty/limits.conf.
Please make sure you have done all the pre-requisites.
Thanks

Illustrator won't run: "unable to set maximum number of files to be opened"

I have an intel macbook pro (core duo with 2GB ram) and a copy of purchased adobe creative suite 2. Other applications in the suite like photoshop, acrobat, etc can run on my mac without any problem. But when I try to run illustrator, it just shows an error message "Unable to set maximum number of files to be opened" and quits. I also installed a trial version of illustrator cs3 and got the same problem. Can anyone help? Thanks.

Error maximum number of files already open error.No Other files can be opened or printed until some are closed

Hi everyone,
While opening a file in Adobe reader 10 in Windows 7,I am getting the error as
"The maximum number of files are already open.No Other files can be opened or printed until some are closed."
Can Anyone help or suggest a setting for this ?
Thanks in Advance

Hello omkar841987,
Could you please let me know how many files have you opened simultaneously.
This count will include files that are being displayed as well as opened (without being shown in the viewer).
Using Reader, you cannot make any setting for the same, but close some of the files before crossing that limit.
It also depends on your OS and memory size as you would need enough memory to open many files at a time.

The maximum number of files have been indexed

Hi
I've just tried using Edge Code with a large project. Upon attempting to use Quick Edit on a class name I got the following error: "Error indexing files. The maximum number of files have been indexed. Actions that look up files in the index may function incorrectly."
After closing the pop-up window, the Quick Editor fails to work.
Are there any plans to increase the size of the index limit? I'm very impressed with the software so far, but not being able to use the quick edit function defeats the purpose of using Edge Code.
Cheers,
Roberto

Hi Memalyn
Essentially, the bare issue is that you have a 500GB hard drive with only 10GB free. That is not sufficient to run the system properly. The two options you have are to move/remove files to another location, or to install a larger hard drive (eg 2TB). Drive space has nothing to do with SMC firmware, and usually large media files are to blame.
My first recommendation is this: download and run the free OmniDiskSweeper. This will identify the exact size of all your folders - you can drill down into the subfolders and figure out where your largest culprits are. For example, you might find that your Pictures folder contains both an iPhoto Library and copies that you've brought in from a camera but are outside the iPhoto Library structure. Or perhaps you have a lot of purchased video content in iTunes.
If you find files that you KNOW you do not need, you can delete them. Don't delete them just because you have a backup, since if the backup fails, you will lose all your copies.
Don't worry about "cleaners" for now - they don't save much space and can actually cause problems. Deal with the large file situation first and see how you get on.
Let us know what you find out, and if you manage to get your space back.

Maximum number of files in a folder ?

Hello, what is the maximum number of files in a folder OS X can handle ?
I used a file recovery software called FileSalvage to save some files of an external 300GB with a corrupted disk directory (unable to repair with the usual repair/recovery programs).
FileSalvage recovered about 435,000 files and sorted them by extension in individual folders, unfortunately it does not recognize the file names and just sequentially names the files per extension.
The .jpeg, .gif and .html folders had up to 75,000 files. After recovery the external FW drives started to behave very strange, unresponsive, just hanging, time-out. I tried on a Mac Mini, iMac G5, an iBook and PowerBook, OS X 10.3.9 and 10.4.3, FW400/800 and USB 2.0 interface, they all had pretty much the same failure mode after a while.
Running Disk Utility on the drives with the recovered FileSalvage folders showed a corrupted directory (invalid file count) and unable to repair, although I could copy most of the folders of the disk (deleted the folders with more than 10,000 files per folder).
I suspect that File Salvage copies more files in a folder than OS X allows, causing unpredicable problems.
Any ideas ?

From "Mac OS X: Mac OS Extended Format volume and file limits"
"Maximum number of files (or files and folders) in a folder … up to 2.1 billion"
According to a note in the document, the above is subject to the drive's size (maximum 16 terabytes in "Tiger") and block size, ie. the number of available blocks.
So it would appear that the number of files you mentioned would be well within theoretical limits, although I suppose there could be a bug in some other part of OS X. Otherwise, maybe there is a problem with the drive...

The maximum number of files already open....

I just started getting a message in adobe reader 9, The maximum number of files are already open. No other files can be open or printed until some are closed. I only have 1 file open. Any suggestions other than getting rid of Adobe!

Try a search of the forum. I faintly remember such a thing being brought up before in the last month or two.

Recommended Maximum Number of Files

Does Apple recommend a maximum number of files per directory for Finder? This is similar to the question posted here at <http://tinyurl.com/24hw7w>, but a little more specific.
This is not about the file system, but about the Finder. Just because the file system can address 2 billion files does not mean it's wise to dump even 1/1,000th of that into a directory, then open it in Finder. Display could slow to a crawl, for example.
I seem to recall that there was an Apple advisory on this, but I cannot find it.

Look at http://docs.info.apple.com/article.html?artnum=25557

Maximum number of files reached

I keep getting a message on my phone that you've reached maximum number of files. Please remove applications and/or files to clear space. When I hit button for help it says to got to www.vzw.com/baplus to find: -FAQs/help -manage contacts -contact support. When I go into my verizon and my device (with my phone number) I get a backup assistance list of another phone on my plan. It shows their number in the upper left corner on the back up assistance. I cannot get to my backup assistance numbers to manage.

Thanks for trying to get to your information already, BrutusgoBucks. Please make sure that when you're visiting www.vzw.com/baplus, log into My Verizon as your mobile number. Going to My Verizon and logging in with the account number will result in seeing the main number registered to that user name instead of your information, even if you select your number later in the page. If you've never created a My Verizon account for your line, no worries! It's easy. Just select register instead of sign in and create an account for your specific line. That way you'll be able to view your line's content on Backup Assistant Plus and the media center.
Thank you

Maximum number displayed files in Folder in Dock?

One of our users has over 800 files saved directly in her Documents folder. We keep this folder in the usual location, and also have it displayed in the Dock as a "list". When she clicks on the folder, about the first half of the files show up - if displayed alphabetically for example, she gets A - M.
Does anyone know if this is fixable? I'm assuming here that there is some maximum number of displayed files which maybe I can fix by editing a .plist or something. It drives her nuts to have to do the "open in Finder" thing half the time, but not the other half of the time (obviously, when she opens this folder as a Finder window everything is there, it is only the display in the Dock which refuses to show all items).
Thanks!

Thanks for the info. There is indeed a maximum number of files that the dock will show in the contextual menu. Yeah, it would be best if the user wouldn't keep everything organized like that, but it isn't possible to lean over someone's shoulder all the time...

MultiFileSelectPopup maximum number of files

Hi,
What is the maximum number of files that can be opened with this command/popup:
MultiFileSelectPopup
Thanks

Hello,
The Windows API limits the input field to 32767 bytes so you will not be able to select more than that number of files. Have a great day!

Maximum number of applications per application set

Hello,
I know maximum number of dimensions per application is 20 in OutlookSoft 4.2.
What about maximum number of applications per application set?
Regards,
Hiroshi Yaji

Hiroshi - I have not encountered a technical limit on the number of applications in an appset. As a practical reality, performance and system administration will dictate how many apps an appset may contain.
On a related note, you could theoretically have more than 20 dimensions in an app. However, I have only worked with one client who asked (needed?) an app with more than 12 dimensions. In that case, usability was an issue due to the complexity in submitting data to an app with that many dimensions.
Hope that helps,
Jeff

Maximum number of File channels in PI system?

Hi Experts
We are replacing a tool into PI system in my company, and because of this we have to create around 350 File (FTP to Unix Fileshare) Sender/Receiver channels. Already there are 100+ File channels running in production system. Is there a limit for having number of File channels in PI system?
please let us know if there is any parameter to check this limitation or ?
Thanks for your help and quick response on this is appreciated.
Thanks,
Giridhar

Hi Giridhar,
Its more of a design approach than limitations of PI.
There is no limitation of number of channels you create in PI. as a gentleman previously mentioned it might create performance issue as all the channels will be polling at a time to retrieve data.
few suggestions:
1. during design talk to the business team and try scheduling the channels. like every day 3hrs (morning 6am to9am) for few interfaces. and other business in evening 5 to 8 pm. (not everytime a business would be sending data. based on the region and other things they would have a time at which data transmission is high). -- this should be done in Prod only.
2. Keep the size of each message to optimal size 1 to max 5mb so that messages get processed fast.
3. configure the channels very proper with Connection mode : per file transfer .
4. in advanced mode set "ftp.timeout" parameter. this will ensure thread is released one the data transfer is complete/or time exceeds.
5. discuss with the business and set the max file size limit in file sender channel. ...etc
there are many other things you can do to manage large amount of channels (especially file channels) in PI system. this will give optimal performance of PI system overall.
Warm Regards,
Senthilprakash.

Maximum number of processor sockets in Windows Server 2012 Datacenter and Standard

I have found no documentation on the technical number of supported processor sockets supported by Windows Server 2012 for the Standard and Datacenter editions.
Some donation websites like Techsoup claim that Datacenter supports 64 physical processors and Standard 8, but I can find no authoritative confirmation of this and those look like extrapolation from Windows Server 2008 R2.
So what are the maximum supported # of processor sockets, assuming you have licenses for all of them, for Datacenter and Standard? Do they differ by edition?
In addition, is it true that the total # of supported logical processors in a single system is 640 w/o Hyper-V? It was originally reported to be that, but since Hyper-V's number doubled from 160 in the Beta to 320 in the RC and RTM, did this double too?

You might find some of the information you are looking for here -
http://download.microsoft.com/download/2/C/A/2CA38362-37ED-4112-86A8-FDF14D5D4C9B/WS%202012%20Feature%20Comparison_Hyper-V.pdf. I know there is one change that is not reflected there. Recently the maximum number of virtual machines supported
in a cluster was raised to 8,000 instead of the 4,000 reflected in this document.
The maximum number of sockets for Standard would be two because that is the maximum number that the license supports. Standard has never supported 8. Prior to 2012, it supported 4, and then the licensing changed with 2012 so that Standard would
be sold per processor (socket) with a maximum of two. Technically, the binaries are the same for Standard and Datacenter, so you can most likely get it to run with more somehow, but it is not a supported configuration.
The maximum number of sockets for Datacenter would be 64 - that has not changed from 2008. I make this statement based on the fact that Datacenter supports a maximum of 64 virtual CPUs when run as a virtual machine. Virtual machines don't have
the distinction of socket versus hyper-thread versus core. They see what is presented to them as a processor. But, I doubt very much that you will find any off-the-shelf 64 socket systems; most vendors are relying on the core densities instead
of socket density in order to deliver the horsepower. The above referenced document still shows 320 as the maximum number of logical processors, with or without Hyper-V.

Maximum number of files and sizes to be Backup

Hi all,
I read somewhere saying that Windows Server Backup 2012 is limited to 2TB (MBR partitions), but can be more for GPT partitions.
What i want to know is, is there limitation on number of files/folder?
Thanks.

Hi,
I assume you are a little confused by partition limitation and backup size limitation.
Here MBR and GPT are for "partition limitation", which means with MBR the largest partition size is 2TB. In GPT, with larger sector size, it supports larger in partition size.
The limitation of Windows Server Backup (WSB) is caused by single file size limitation - WSB creates a VHD(x) file for saving backups. Currently a single file size is limited in 2TB which causes the WSB limitation. See:
