# Startup and Application Folder

Valued Contributor

Dear Community,

I always get confused with the startup folder and application folder, custom_dirs.dat file and environment variables.  Where in the UG documentation provides a good explanation of how and where to setup these files and environment variables.

Thanks.

I suspect it is in the Programmer's Guide, but here is a cheat sheet you can use in the meantime:

The simple way to define the correct "application" or "startup" directory is to
check and see if you have an environment variable called UGII_USER_DIR pointing
to some directory.

If you do, then create a directory called "application" in that directory, and
create one called "startup" in the same directory.

If you do not have UGII_USER_DIR defined, you can set it in the Windows Control
Panel, under System -> Advanced -> Environment Variables.

For example, you might have UGII_USER_DIR pointing to "D:\user_dir\".  Then you
would create a directory called "D:\user_dir\application" and put the .dlg or .dlx file in that directory.

You can also create a "startup" folder under "D:\user_dir\", for .DLLs that you want to run when NX starts.

If you aren't sure about that environment variable, select Help->NX Log File from
the main menu, and then search for UGII_USER_DIR - it may be a case sensitive search.

That's the simple method.  There is a more complicated method described below.

/*--------------------------------------------------------------------------*/

Here is the other method, which adds one more layer of complexity, but also allows

You can create a simple text file with a list of directories in which you want NX
to look for "application" and "startup" directories.  This text file could contain
only one directory, or as many directories as anybody would reasonably need.

The file just needs to have each directory on a separate line.

So the file could look like this:

D:\user_dir

Or it could look like this:

D:\user_dir
D:\designers
D:\checkers
D:\path\to\some\directory
M:\my\network\drive

(and so on)

And NX would look for "application" and "startup" directories UNDER each of the listed directories, in the order that they appear in the file.

You can call this file anything you want, but in our docs we usually call it
"custom_dirs.dat", so that it is easy to recognize.

Once you have the file created, you have to point at it with a particular environment variable called UGII_CUSTOM_DIRECTORY_FILE.  Be sure that the definition includes the complete path and file name, not just the name.  For example, UGII_CUSTOM_DIRECTORY_FILE could be set to "D:\my_data\custom_dirs.dat".

(You may see a similar variable called "UGII_UG_CUSTOM_DIRECTORY_FILE" - don't get them mixed up, and don't redefine the longer one.)

In the NX10 docs, see NX Open -> NX Open Programmer's Guide -> Executing NX Open Automation -> Application Directory Structure.

Note that in the custom_dirs.dat file you can reference your directories using environment variables also. E.g.: ${nxAppDir} This way you could use the same custom_dirs.dat file at different sites that may have different root locations for the NX custom directories. The environment variables could be defined in your NX startup bat file.

For another project, I used the UGII_USER_DIR approach and that worked fine.

-Create a new folder in "C:\users\username\yourapplicationname"

Now I am trying the custom_dirs.dat approach but it does not seem to be working

$UGOPEN\SampleNXOpenApplications\Python\BlockStyler\MatrixOperations -I created an environment variable UGII_CUSTOM_DIRECTORY_FILE=C:\Program Files\Siemens\NX 10.0\UGII\menus\custom_dirs.dat I placed the Matrixoperations .dlx file in the UGOPEN\SampleNXOpenApplications\Python\BlockStyler\MatrixOperations folder Then in NX10, I used the journal to run the Matrixoperations.py file and I get an error message that says "None type" object has no attribute "Show" # Re: Startup and Application Folder Gears Esteemed Contributor First: I would NOT modify ANY files in the install folder tree. But that aside...The file may need to be in the "application" subfolder, i.e. UGOPEN\SampleNXOpenApplications\Python\BlockStyler​\MatrixOperations\application If it is meant to be run at NX start, then put in in the "startup" subfolder: UGOPEN\SampleNXOpenApplications\Python\BlockStyler​\MatrixOperations\startup Ken Ken Akerboom Sr CAx Systems Engr, Moog, Inc.

@AlexLee Is there a specific reason, that you choose to keep your .dlx files  in the base directory( as pointed by the UGII_BASE_DIR variable ? Is it because that NX was unable to identify, if you kept it in a directory other than the base directory?. I have tried all the steps and I am trying to make a applications folder in C:\Users\myusername\Documents\TestFolder\applications. But NX is unable to detect the .dlx file when I execture the .dll file.

It is important that your directory name is "application" - there is no "s" on the end.

Then define the folder above it with UGII_USER_DIR - or list it in your custom_dirs.dat file.

So for example, if you set:
