I recently installed some new software and I continue to get a an error that says files=70 and something to the effect that I need to increase the number.  I tried increasing the number in the config.sys file to 150 and rebooted. I still got the error when I tried to go into the program.

How do I change file handles?  How do I get into config.nt to change values?

Your help is greatly appreciated.

You can open config.nt from the %systemroot%\system32 folder.  You can open it with notepad or any other text editor.

Changing the file=70 to a higher number should give me more file handles?Correct?

Will this ask me to reboot the system?

files=70 will increase file handles, and in most cases, a reboot is not necessary.  Simply close the application and relaunch it.  I have however encountered a couple of situations where a reboot appeared to be required.

NT does not require "file handle" entry in the config.nt file. If this was a 16bit application, try running this in its own memory( start-> run-> executable and check the "run in separate memory space" box).

madari, NT does require a files= entry in the config.nt file for some 16-bit apps.  I have a couple I could show you.

What is the max on the file handles?  What should determine the number of file handles?

The application's needs would determine that.  There was a problem with a previous service pack with files= entries above 255 causing problems, but that has been corrected.  I am not sure what the limit would be, maybe limited only by free memory.

I recently went into a business with a server that has only 32MB RAM.  The system said the file handles needed to be increased.

What is the correlation with the memory? Especially, dealing with 32MB?

Each additional file handle would use more memory, but the amount is minimal, so the impact on increasing the file handles would be minimal.

CONFIG.NT and AUTOEXEC.NT are ONLY used when an NTVDM is kicked off.
You can make changes and they become effective next time you start another NTVDM session.

config.sys is NOT read by NT, so making changes in it won't make any difference.

What's this software of yours ?

Is it NT compliant ?

With an error message like that, I don't think it is !

NT's a 32bit operating system - it will have millions of spare file handles, so I don't think this is the real problem here.

The software is HUD Manager 2000.  The software was installed once before and it expired or something, so I had to reinstall it.

Can you get hold of a 32bit version maybe ?
Who makes this product ?
