Hello,
I would like to check the free disk space (on the render server) before sending a netrender job from maxscript. SpaceOnDisk should do what I need, but it only supports the working disk (“Currently, this only returns correct results for one disk, your workdisk (given by .workdisk)”).
I can’t find a similar function in dotnet either.
Any suggestions?
(
drives = (dotnetclass "System.IO.DriveInfo").GetDrives()
for d in drives do
(
format "Name: %
" d.Name
if d.IsReady then
(
format " Available free space: % bytes
" d.AvailableFreeSpace
format " Total available space: % bytes
" d.TotalFreeSpace
format " Total size of drive: % bytes
" d.TotalSize
)
else
(
format " The device is not ready.
"
)
)
)
Have you seen my post here?

Or you download my KClasses and do something like this
Code:
dotnet.loadassembly @“C:\KClasses.dll”dnGet=dotnetObject “KClasses.DnGetDiskFreeSpaceEx”
dnGet.dnGetDiskFreeSpace @”\yourserver\shared”
print (((dnGet.freeBytes / 1024) / 1024) / 1024)Values are returned in Long. Cheers!
Denis, that would only work on mapped drives, right?
BTW, if you want more info here’s this link:

Kameleon is right. My solution is just for mapped drives.
let’s ask c# for some help:
global DriveAssembly
fn CreateDriveAssembly forceRecompile:on =
(
if forceRecompile or not iskindof ::DriveAssembly dotnetobject or (::DriveAssembly.GetType()).name != "Assembly" do
(
source = ""
source += "using System;
"
source += "using System.Runtime.InteropServices;
"
source += "public class DriveOps
"
source += "{
"
source += " [DllImport(\"kernel32.dll\", CharSet = CharSet.Auto, SetLastError = true)]
"
source += " internal static extern bool GetDiskFreeSpaceEx(
"
source += " string directoryName,
"
source += " out long freeBytesAvailable,
"
source += " out long totalNumberOfBytes,
"
source += " out long totalNumberOfFreeBytes);
"
source += " public static long[] GetDiskInfo(string directoryName)
"
source += " {
"
source += " long freeBytesAvailable, totalNumberOfBytes, totalNumberOfFreeBytes;
"
source += " try { GetDiskFreeSpaceEx(directoryName, out freeBytesAvailable, out totalNumberOfBytes, out totalNumberOfFreeBytes); }
"
source += " finally { };
"
source += " return (new long[] { freeBytesAvailable, totalNumberOfBytes, totalNumberOfFreeBytes });
"
source += " }
"
source += "}
"
csharpProvider = dotnetobject "Microsoft.CSharp.CSharpCodeProvider"
compilerParams = dotnetobject "System.CodeDom.Compiler.CompilerParameters"
compilerParams.ReferencedAssemblies.Add("System.dll");
compilerParams.GenerateInMemory = true
compilerResults = csharpProvider.CompileAssemblyFromSource compilerParams #(source)
DriveAssembly = compilerResults.CompiledAssembly
)
)
-------------------------------------------------------------------------
CreateDriveAssembly forceRecompile:on
global getDriveSpace = (DriveAssembly.CreateInstance "DriveOps").GetDiskInfo
getDriveSpace "c:"
probably it’s exactly the same as Kameleon does do. So give him the credit
Yeah, that’s what I have on my custom dll, I never got that maxscript assemblies thingy you do… since I need to try, error, see VB messages for what I did wrong, try, error, etc etc Oh and I dont mind dividing the props with the Uber DenisT It’s an honor hehe
That’s just brilliant guys, many thanks.
I’ve tested it with
getDriveSpace @"[\\Computername\Render\](file://ComputernameRender)"
and that works great.
(Sorry for the late response)
