Hi
I would like to know when creating interface for a digital asset, how I can define a file pattern in File parameters for “folders” or “directories”; So that when the user is going to choose a file, when inside a folder and clicks Accept, it DOES accept the folder and doesn't need to click on a file.

But if you create a File parameter and Select only one Folder (Don't move inside folder) and Press Accept ,You will take just Folder path :?

However If you wanna select a File ,But Houdini put only Folder path in the parameter ,I think you should use Python Script :idea:

Write a simple python script to for extracting folder(directory) path from full file path ,then use this script in the “Callback Script” in the “Type Properties” window

*** Create hdaModule and call it in the “Callback Script” from File Parameter ***

Check Attached FIle :wink:

Hi Varomix,

I know it's been years, but I just needed that.
The filter I used:


What is will do is omit everything that have a dot in the name, so not the most elegant solution but works for me.

Houdini 16.5.202 Added a “File - Directory” parameter type, which specifies a path to a directory and opens the file chooser in directory selection mode. In the HDK, this can be done with PRM_DIRECTORY.
