Welcome to Lesson 7 of the HTVRONT E15 Embroidery Machine tutorial series. In Lesson 6, we covered upper thread tension using the "I" test pattern. Today, we're taking a step away from tension and mechanics to focus on something just as important: expanding your design library.
When you purchase the E15 embroidery machine, you'll find that the machine comes with 40 built-in machine embroidery designs already installed. But if you have other digitized embroidery files — designs you've purchased, downloaded, or received from a client — you can upload them to the E15 through a USB drive.
The E15 15-needle embroidery machine supports DST and DSB file formats — the two most widely used embroidery file formats in the industry. This means you can import designs from nearly every major digitizing software and design marketplace. In this tutorial, we'll walk through the complete USB upload process step by step.
Key Takeaways
The E15 accepts DST and DSB file formats — the two industry-standard embroidery file formats.
Your imported design goes into the Pattern Library and gets assigned a number you can find it by later.
Any standard USB drive works — just plug it into the USB port on the machine.
The import takes only seconds — no special software is required on the machine side.
Once imported, designs stay on the machine — you don't need to keep the USB drive plugged in.
Importing a Design from USB Drive: Step by Step
Follow these steps in order. The process takes less than a minute once the USB drive is ready.
Step 1: Turn On the Machine and Insert the USB Drive
First, turn on the E15 embroidery machine. Insert the USB drive containing your embroidery design into the USB port. The USB port is typically located on the side or rear of the machine — check your machine's layout if this is your first time using it.
Pro Tip: Keep your designs organized on the USB drive. Naming files clearly with descriptive names (like "sunflower-logo-3inch.dst" instead of "design1.dst") makes it much easier to find the right design during the import process.
Step 2: Open the USB Menu
Once the USB drive is detected, tap the USB icon on the touchscreen.
Step 3: Tap Import Pattern
From the USB menu, tap Import Pattern. This opens the file browser showing all compatible embroidery files on the USB drive.
Step 4: Select Your Design
Browse the files on your USB drive and select the design you want to import. Once selected, tap Send to Pattern Library.
Step 5: Assign a Number to the Design
Assign a number to the imported design. For example, 479. This number is how the machine identifies the design in the Pattern Library — so pick a number that you'll remember, or note it down if you're importing several designs at once.
Note: If the number you choose is already in use, the machine will ask you to pick a different one. Keep a simple log (or take a photo of the screen) of which numbers you've assigned to which designs to avoid confusion later.
Step 6: Find the Design in the Pattern Library
Return to Pattern Select and find the design with the assigned number. Your newly imported design should now appear in the library alongside the 40 built-in designs.
Step 7: Confirm the Import Is Complete
When you can see and select the design in the Pattern Library, the import is complete. You're now ready to edit, position, and stitch the design just like any of the built-in patterns.
That's it — your design is now stored on the machine and can be stitched any time without needing the USB drive plugged back in.
Quick Import Checklist
Run through these points before starting your import:
✅ Machine turned on and running normally
✅ USB drive inserted and detected
✅ Design file is in DST or DSB format
✅ USB icon tapped to open the USB menu
✅ Import Pattern selected
✅ Design file selected and sent to Pattern Library
✅ Design number assigned and noted
✅ Design confirmed in Pattern Select
✅ USB drive safely removed after import

Conclusion
You've now learned how to import a design from a USB drive onto the E15 embroidery machine. This opens up your creative possibilities significantly — you're no longer limited to the 40 built-in designs. You can now work with:
Designs purchased from embroidery marketplaces like Etsy, Creative Fabrica, or Design Bundles
Custom designs digitized by a professional service
Designs from your own digitizing software
Client-supplied embroidery files
Once a design is imported, it stays on the machine — so you can build up a personal Pattern Library over time and keep your most-used designs ready to stitch at any moment.
Where to get more designs: HTVRONT's IdeaStudio software supports the E15 15-needle embroidery machine and offers 300 free embroidery patterns to get you started. You can download IdeaStudio to explore more interesting and beautiful embroidery patterns. You can also purchase more professional, designer-made original embroidery designs directly within IdeaStudio.
In the next lesson, we'll cover How to Import Embroidery Designs Using HTVRONT IdeaStudio — how to browse, download, and transfer designs from IdeaStudio to the E15 machine over WiFi. This is the workflow that lets you skip the USB drive entirely and build your design library directly from the app.
Have questions about importing designs to your E15?
What file formats does the E15 support for USB imports?
The E15 supports DST and DSB embroidery file formats. These are two of the most common industry-standard formats used across digitizing software, embroidery marketplaces, and commercial design libraries. If your design is in a different format — like PES, JEF, EXP, or VP3 — you'll need to convert it to DST or DSB using a file converter before importing. Many digitizing software packages include this conversion capability built-in.
Do I need a special USB drive to import designs to the E15?
No — any standard USB drive works. The E15 uses the USB drive simply as a file transfer medium, so there's no special format or proprietary drive required. A standard USB 2.0 or USB 3.0 flash drive with enough storage space for your design files is all you need. For best results, format the drive as FAT32 to ensure broad compatibility with the machine.
Can I import multiple designs at once?
Yes — you can import designs one at a time, and each one will get its own assigned number in the Pattern Library. If you're importing several designs, keep a written record or take photos of the screen as you assign numbers so you can find them easily later. Some users prefer to import a batch of designs at the start of a project week, then reference the assigned numbers throughout production.
Do I need to keep the USB drive plugged in after importing?
No — once a design is imported into the Pattern Library, it's stored on the machine's internal memory. You can safely remove the USB drive after the import is confirmed. This means you can import a batch of designs onto the machine, remove the drive, and stitch any of them at any time without needing the USB drive plugged back in.
What should I do if the USB drive isn't detected?
Start by checking the file system format of the USB drive. The E15 works most reliably with FAT32-formatted drives. If your drive uses a different format (like NTFS or exFAT), reformatting it to FAT32 often resolves detection issues. Also make sure the drive is fully inserted into the USB port and that the machine is powered on. If the problem persists, try a different USB drive to rule out a hardware issue with the drive itself.
Will the assigned design number affect how the design stitches?
No — the assigned number is only used for identifying the design in the Pattern Library. It doesn't affect the stitch-out, thread order, or any other aspect of the design. Choose numbers that are convenient for you — sequential numbers, or numbers that match a project or client code. Just avoid reusing a number that's already assigned to another design on the machine.
