# We built bulk upload and product variants for digital sellers - here is how they work

If you have ever tried listing 100+ digital products on a marketplace, you know the drill - fill a form, upload files, set pricing, repeat forever. We just shipped two features on [3DIMLI](https://www.3dimli.com) that kill this workflow entirely.

## Bulk Upload via Watch Folders


![Bulk Upload Feature](https://pub-652cba53b57e4ec6bdbe86d25d91caf9.r2.dev/blog/3dimli-bulk-upload-feature.png)

No CSV imports. No web forms. No API calls needed.

The [3DIMLI Desktop App](https://support.3dimli.com/Guides/bulk-uploads%20and%20watch%20folder) has a watch folder system. You point it at a directory, and every subfolder becomes a product draft.

### Folder structure

```plaintext
watch-folder/
 fantasy-sword/
 main.png
 angle-1.jpg
 sword.fbx
 description.html
 tags.txt
 pixel-art-brushes/
 main.jpg
 brushes.zip
 description.html
```

The app auto-detects:
- **Product title** from folder name ("fantasy-sword" becomes "Fantasy Sword")
- **Main image** from files named main.*, thumbnail.*, or cover.*
- **Gallery images** from remaining image files (up to 16 total)
- **Download files** from supported formats (.blend,.fbx,.psd,.zip,.exe,.pdf, etc.)
- **Product type** from the download file extensions
- **Description** from description.html or description.txt
- **Tags** from tags.txt (one per line or comma-separated)

### Live sync

The watch folder is not a one-time import. It monitors continuously:
- Add files -> they appear in the draft
- Rename folder -> title updates
- Edit description.html -> draft updates
- Delete folder -> draft removed

### Bulk publish

Once drafts look good, select all (or specific ones) and hit "Publish Selected". Products go live one by one with a progress indicator.

**Limits:** 1 GB per download file, 2 MB per image, 16 images max, 1500 char descriptions, 6 tags.

The desktop app runs on Windows, macOS (Intel + Apple Silicon), and Linux.

## Product Variants


![Product Variants Feature](https://pub-652cba53b57e4ec6bdbe86d25d91caf9.r2.dev/blog/3dimli-product-variants-feature.png)

The second feature solves a different pain point - product duplication.

If you sell software with Windows and Mac builds, or a 3D model pack with Standard and Deluxe editions, you used to need separate listings for each. Now you create one product with variants.

Each variant gets its own:
- **Pricing** (different price per edition)
- **Download files** (different builds per platform)
- **Media** (different preview images)
- **Colors and attributes** (buyer picks what they want)

One product page. Multiple options. No cloning.

Works great for:
- Platform-specific builds (Win/Mac/Linux)
- Standard vs Pro vs Enterprise editions
- Bundle packs vs individual items
- Color/theme variations

## Why this matters

Most digital product platforms either do not support bulk operations at all, or they charge you 10-30% commission for the privilege.

[3DIMLI](https://www.3dimli.com/features) charges **8% on Flexible (only on finalized sales) or 0% on Fixed ($25/month, annual saves 17%)**. You get instant payouts. Buyers in 200+ countries.

The platform is **on the Flexible plan (free to start, 8% commission on sales)** - no credit card needed. If you are building digital products (3D models, software, plugins, game assets, graphics, audio, e-books, AI models), [create a store](https://www.3dimli.com/register) and try bulk upload today.
