I’m trying to create a Unity package with prefabs, scenes, and everything works fine except for my npmDef files. It says there are some hidden folders that aren’t being copied. How can I resolve this?
The issue you’re facing with hidden folders not being copied during package creation in Unity relates to the handling of .npmdef files and their associated directories. These files often manage dependencies that are stored in hidden folders marked with a ~ symbol at the end of the folder name. This is to prevent Unity from importing the files in these directories directly.
Here’s how you can resolve this:
-
Check if the Folder Exists:
Make sure that the hidden directories (ending with~) actually exist. Sometimes, they might not be created or properly linked, especially if the.npmdefwas moved manually (see the documentation) (see the documentation). -
Ensure Proper Directory Linking:
When moving or copying.npmdeffiles, ensure that their corresponding hidden folders are also relocated correctly. The system often expects these directories to be aligned properly with the.npmdeffiles (see the documentation). -
File System Limits:
Check if there are any filesystem permissions or locks that might be preventing these folders from being copied properly. Sometimes, processes might lock these directories, preventing their movement (see the documentation) (see the documentation). -
Unity Editor Logs:
Open the Unity Editor logs to check if there are any errors or warnings related to file system operations. This might give you more clues if something is going wrong during the package creation (see the documentation).
If you follow these steps and ensure all directory structures are correctly set up and verified in Unity, this should help mitigate the issue.
If you need further assistance, I would recommend checking Unity’s Asset Management settings and make sure all paths and folders are correctly defined according to your project’s structure (see the documentation).

Hello,
What part is saying the folders could not be copied? The hidden folder will be copied together with the npmdef asset if you have one in Unity. So you can either try to move your npmdef to your new package from within Unity’s Project window or you can try closing Unity and copying the directory over manually.
Hi Marcel, so my problem is that I create a Unity package with prefabs, scenes, materials, etc. The issue is that when I try to access the npmdef files, I get this error. I found a temporary solution, which is to make the npmdef files into a zip file and then extract them into the project. However, I imagine there must be another way to do this to install the npm files without any issues.
Would you be able to provide repro steps and a project folder for us to try out the steps you’re doing here? Thanks!
Hi Herbst, yes, of course! I just submitted a bug report through Unity. I hope that’s what you need; otherwise, let me know if there’s another way to share it. Thank you very much!
