# Invalid File Structure Error

> Human Generator for Blender documentation. Web version: https://humgen3d.com/docs/faq/invalid-file-structure-error

Did you by chance download the content packs with Safari? Safari is known to auto-unzip files you download. Because Human Generator uses a custom file structure for the content packs, you can't simply re-zip the files.

## The easiest ways to get around this issue are:
- Turn off auto-unzipping in Safari, and re-download the packs.
- Download the packs with another browser, like Chrome.

## If you don't want to re-download:
If your internet speeds would make it very slow to re-download the packs, you can manually re-zip the content packs without root folder like this:
1. Open each pack that was automatically unzipped by Safari, and select all folders inside:

2. Ctrl+Click or Right Mouse button click and press 'Compress':

 3. Rename the created Archive.zip to the exact same name as the content pack folder you downloaded:
