Plugin checker

*** EXAMPLE ***

First we need to define some array with plugins that you need to check, let say "plugs" array or you cen use some extension instead in this form #(".dlm", ".dlo")
Below is a list of the extensions and the plug-in types :

BMI - Bitmap Manager IO DLLs.
BMF - Bitmap Manager Filter plug-ins.
BMS - Bitmap Manager Storage DLLs.
DLB - Shader plug-ins.
DLC - Controllers.
DLE - Scene Export plug-ins.
DLF - Font Loaders.
DLH - Sampler plug-ins
DLI - Scene Import plug-ins.
DLK - Filter Kernels (Anti-aliasing filters)
DLM - Modifiers.
DLO - Procedural Objects.
DLR - Renderers.
DLS - Object Snap plug-ins.
DLT - Materials and Textures.
DLU - Utility plug-ins.
DLV - Rendering Effects
DLX - MAXScript extension plug-ins.
FLT - Image Filter plug-ins.
GUP - Global Utility plug-ins.
MS - Maxscript
MSE - Encrypted maxscript

Aruguments of "checkPlugsVersion" fn
" dir: "
- here you can add any directory ei. plugins folder path
- if this argument is not supplied with some path MAXROOT folder
- will be checked
" plugsFilenames: "
- here you need to add "plugs" array that I mentioned earlier
- example

plugs = #("Quad Chamfer.dlm","MultiTexture_max2014_64.dlt","bulgeomatic.dlm")

- if this case you not need to supply " ext: " because function will use only
- extensions from "plugs" array
" ext: "
- supply this argument only if you want to check print installed
plugins by extensions
- to print installed all plugins then not supply "plugsFilenames"
and "ext" argument. Simply run below code:

checkPlugsVersion()

-----------------------------------------------------------------------
--#1 example: check plugs in max plugins folder

plugs = #("Quad Chamfer.dlm","MultiTexture_max2014_64.dlt","bulgeomatic.dlm","BerconMaps_2013_64.dlt")
folder = (getDir #maxroot) +"plugins"
checkPlugsVersion dir:folder  plugsFilenames:plugs

--#2 example: check plugs in max root folder

plugs = #("Quad Chamfer.dlm","MultiTexture_max2014_64.dlt","bulgeomatic.dlm","BerconMaps_2013_64.dlt")
checkPlugsVersion plugsFilenames:plugs

--#3 example: check modifier and material plugs in max plugin folder

extensions = #(".dlm",".dlt")
folder = (getDir #maxroot) +"plugins"
checkPlugsVersion dir:folder ext:extensions 

I hope this is helpful

;)

fn checkThisPlugins=
(
	plg2Check= #("Quad Chamfer.dlm","MultiTexture_max2014_64.dlt","bulgeomatic.dlm","BerconMaps_2013_64.dlt")
	thePath = ((getDir #maxroot) +"plugins"+"\\")
	
	for i in plg2Check do
	(
		if doesFileExist (thePath+i) then 
			(
				format "% installed !\n" i
			)
		else
			(
				format "--> % not installed !\n" i
			)
	)
)

checkThisPlugins()

*** DOTNET VERSION ***

fn checkPlugsVersion dir: plugsFilenames: ext: =
(
local sioDir = dotNetClass "System.IO.Directory"
local sioFile = dotNetClass "System.IO.File"
local sioPath = dotNetClass "System.IO.Path"
local sioSearchOptAll = (dotNetClass "System.IO.SearchOption").AllDirectories

if dir == unsupplied or not sioDir.exists dir do dir = getDir #maxroot
if allFiles.count == 0 do return (messageBox "This directory not contains any file")
local allFiles = sioDir.GetFiles dir "*.*" sioSearchOptAll

if plugsFilenames != unsupplied then
(
local plugNames = #()
ext = for p in plugsFilenames collect
(
append plugNames (tolower (sioPath.GetFileNameWithoutExtension p))
sioPath.getExtension p
)
allFiles = for f in allFiles where findItem ext (tolower (sioPath.getExtension f)) > 0 collect
(
(tolower (sioPath.GetFileNameWithoutExtension f))
)
for n = 1 to plugNames.count do
(
if findItem allFiles plugNames[n] == 0 then format "Plugin % is not installed!\n" plugsFilenames[n]
else format "Plugin % is already installed!\n" plugsFilenames[n]
)
)
else -- with this statement you can print all installed plugins by given extensions
(
if ext == unsupplied do
(
ext = #(".bmi", ".bmf", ".bms", ".dlb", ".dlc", ".dle", ".dlf", ".dlh", ".dli", ".dlk", ".dlm", \
".dlo", ".dlr", ".dls", ".dlt", ".dlu", ".dlv", ".dlx", ".flt", ".gup", ".ms", ".mse")
)
for f in allFiles where findItem ext (tolower (getfilenametype f)) > 0 do print f
)
free allFiles
)

DoesFileExist not works in your code, because nPc[1] is an array. To works use this

doesFileExist (nPc[1][1])
