Symbolic Pathnames

You can use symbolic pathnames in the form $<name> anywhere a filename can be supplied to MAXScript.

This support was added in 3ds Max 4 and was largely enhanced in 3ds Max 9.

Any filename you provide to MAXScript can begin with a '$' followed by one of the symbolic directory names below.

The following symbolic names are recognized:

Index	Symbolic Name	Directory
1	$max	Main 3ds Max executable directory
2	$maps	First directory in Maps directory config*
3	$scenes	3ds Max Scenes directory
4	$fonts	Fonts directory
5	$imports	File Imports directory
6	$exports	File Exports directory
7	$sounds	Sounds directory
8	$matlibs	Material Libraries directory
9	$scripts	Scripts directory
10	$startupScripts	Auto-load startup scripts directory
11	$plugins	First in the Plug-ins directory config*
12	$plugcfg	Plugin configurations directory
13	$images	Images directory
14	$ui	User Interface files directory
15	$macroScripts	macroScripts in UI directory
16	$web	Web downloads directory
17	$temp	System temp directory
18	$renderPresets	Render presets directory
19	$help	Help files directory
20	$expressions	Expressions directory
21	$previews	Previews directory
22	$maxstart	Directory of MAXSTART.MAX
23	$vpost	Video post directory
24	$drivers	Drivers directory
25	$autoback	Auto-backup directory
26	$marketDefaults	Market Defaults directory
27	$icons	Icons directory
28	$maxSysIcons	System icons directory
29	$renderOutput	Render output directory
30	$animation	Animations directory
31	$archives	Archives directory
32	$photometrics	Photometric files directory
33	$renderAssets	Render Assets directory
34	$userScripts	User Scripts directory
35	$userMacros	User Macroscripts directory
36	$userStartupScripts	User Startup Scripts directory
37	$userIcons	User Icons directory
38	$maxData	Max Data (Root) directory
39	$downloads	Downloads directory
40	$proxies	Bitmap Proxies directory
41	$assemblies	Assemblies directory
42	$hardwareShadersCache	Hardware shaders direcotory
43	$plugcfg_ln	Plugcfg_ln directory
44	$ui_ln	UI_LN directory
45	$autodeskcloud	Autodesk cloud directory
46	$userStartupTemplates	Startup templates directory
47	$privateExchangeStoreInstallPath	Private Exchange Store install directory
48	$publicExchangeStoreInstallPath	Public Exchange Store install directory
54	$CFD	User CFD scene assets directory
54	$systemImage	System scene images directory
54	$systemPhotometric	Photometric light definition (.ies) file directory
54	$systemSound	System sene sound assets directory
54	$systemCFD	System CFD scene assets directory
54	$pageFile	Temporary page file directory (in 3ds Max 2018.4 Update and later).

Please note that these are similar to the 3ds Max System Directories filetype_names which start with a "#"and are used as arguments to the GetDir() and SetDir() methods.

The following example will open the file "foo.ms" in the current 3ds Max Scripts directory.

EXAMPLE

fileIn "$scripts\foo.ms"

In 3ds Max 9 and higher , the $maps and $plugins symbolic pathnames can also specify an index. In this case, the indexed directory will be used.

EXAMPLE

"$maps[2]\\mybitmap.tga"

When no index is provided, the first map resp. plugins path will be used.

SymbolicPaths Struct

In 3ds Max 9 and higher, the SymbolicPaths struct provides methods to access existing and define new symbolic paths:

symbolicPaths.numPaths()

Returns the number of symbolic path names. This includes both system and user-defined path names

   

symbolicPaths.getPathName<index>

Returns the indexed symbolic path name.

EXAMPLE

for i =1 to symbolicPaths.numPaths() do format "% : %\n" i (symbolicPaths.getPathName i)

symbolicPaths.isPathName <string>

Returns true if the string corresponds to a symbolic path name, false otherwise.

EXAMPLE

symbolicPaths.isPathName "$maps" true symbolicPaths.isPathName "$map" false

symbolicPaths.getPathValue {<index> | <string>}

Returns the path associated with the specified symbolic path name (specified either by index or by name string).

EXAMPLE

symbolicPaths.getPathValue 2 "C:\Program Files\Autodesk\3ds Max 2012\maps" symbolicPaths.getPathValue"$maps" "C:\Program Files\Autodesk\3ds Max 2012\maps"

symbolicPaths.numUserPaths()

Returns the number of user-defined symbolic path names.

   

symbolicPaths.getUserPathName <index>

Returns the indexed user-defined symbolic path name.

   

symbolicPaths.isUserPathName <string>

Returns true if the string corresponds to a user-defined symbolic path name, false otherwise.

   

symbolicPaths.getUserPathValue {<index> | <string>}

Returns the path associated with the specified user-defined symbolic path name

   

symbolicPaths.setUserPathValue {<index> | <string>} <filepath>

Sets path associated with the specified user-defined symbolic path name

   

symbolicPaths.addUserPath <string> <filepath>

Adds user-defined symbolic path name and path

   

symbolicPaths.removeUserPath {<index> | <string>}

Removes user-defined symbolic path name

   

symbolicPaths.expandFileName <filename>

Returns expanded file nane

EXAMPLE

symbolicPaths.numUserPaths() --check foruser path- none by default 0 symbolicPaths.addUserPath "$test" "c:\\test" --define new user path OK symbolicPaths.numUserPaths() --check foruser path- there is one! 1 symbolicPaths.isUserPathName "$test" --is a user symbolic path? true --See if $temp is a user symbolic path. --NOTE that $temp is aSYSTEMsymbolic path, --but not aUSERsymbolic path: symbolicPaths.isUserPathName "$temp" false symbolicPaths.getUserPathName 1 --get the name of the first path "$test" symbolicPaths.getUserPathValue 1 --get the first path "c:\test" symbolicPaths.getUserPathValue "$test" --get the path by name "c:\test" symbolicPaths.setUserPathValue "$test" "c:\\another\\path" --change OK symbolicPaths.getUserPathValue "$test" --see if itchangeg? "c:\another\path" symbolicPaths.expandFileName "$test\\somefile.txt" --expand a path "c:\another\path\somefile.txt" symbolicPaths.removeUserPath "$test" --remove the user path OK symbolicPaths.numUserPaths() --there are no user paths left 0
