Hello, could anyone help me with finding a way to delete a folder and its contents to the recycle bin? I’ve searched online and it seems that it can only be done through visual basic with this line:
FileIO.FileSystem.DeleteDirectory (file, FileIO.UIOption.OnlyErrorDialogs, RecycleOption.SendToRecycleBin)
however I don’t know how to execute vb code through maxscript.
In general, could you point me to a tutorial / example of how to execute compiled code in c# & vb because I want to learn how to do it. Thanks in advance!

(
dotnet.loadAssembly "Microsoft.VisualBasic.dll"
FileIO = dotnetclass "Microsoft.VisualBasic.FileIO.FileSystem"
UIOption = (dotnetclass "Microsoft.VisualBasic.FileIO.UIOption").OnlyErrorDialogs
RecycleOption = (dotnetclass "Microsoft.VisualBasic.FileIO.RecycleOption").SendToRecycleBin
Directory = "C:\THE_FOLDER_TO_DELETE"
if (FileIO.DirectoryExists Directory) then
(
FileIO.DeleteDirectory Directory UIOption RecycleOption
)else(
messagebox "Directory not found."
)
)

Hi, I am not an expert in scripting/coding… Still I would like share my thoughts…
- the best way to go is to find a dos command line equivalent for the same…
Checkout http://www.maddogsw.com/cmdutils/
If this is feasible for you, you could easily call shellexecute and run this recycle from maxscript.
- If you have provision to access socket from maxscript, which I think there is…
You can write an application which could listen and execute the same for you outside max.
Again, I have very limited knowledge of maxscript, so forgive if this is not feasible.

deleteFile(), HiddenDOSCommand()
are these not helpful?
May 06, 2016 9:31 pm
deleteFile can’t delete folders and its contents. It works fine with single files but not directories.
The hidden dos commands have a delete function, but it delete things permanently, not send it to the recycle bin, which I want to do because I want to be able to recover in case of a mistake.
sioDir = dotNetClass "System.IO.Directory"
if (SIODir.Exists folder) do SIODir.Delete (folder) true
also deletes things directly.
I’d like to not depend on external programs to delete things, because I’d like to keep my script self-contained. I’ll consider it once I’ve run out of options
From some of the research I’ve done you can delete to recycle bin through shell with some command called SHFileOperation, or you can delete with the vb code I posted above. There may be more, but I would like to see how the vb code way would work preferably, so that I can learn how to do that, but whatever works.

here is a good explanations how to move into recycling bin, and the working c# solution.

So many different ways to do the same thing! Thank you everyone for the help!
