You bought or downloaded a design, copied it to a USB stick, plugged it in, and the machine shows nothing. Or it shows the file but won't open it. This is one of the most common emails we get, and in almost every case the design itself is fine. The problem is the format, the way the file was copied, or a limit built into the machine.
Work through the checks below in order. Most people find the cause in the first three.
1. The file is in the wrong format for your machine
Every machine brand reads its own stitch file format. A machine will simply ignore files it doesn't understand, so they never appear on screen. Common pairings:
- Brother and Baby Lock: PES
- Janome: JEF
- Husqvarna Viking: HUS or VP3
- Pfaff: VP3
- Bernina: EXP
- Singer: XXX
- Tajima and most commercial multi-needle machines: DST
Check your manual for the exact list, because some models read more than one format. If you only have the wrong one, don't just rename the extension; changing ".dst" to ".pes" doesn't convert anything. Our guide on how to convert DST to PES and other formats walks through doing it properly.
2. The file is still inside a ZIP folder
Many design downloads arrive as a .zip file containing several formats. Embroidery machines cannot open ZIP archives. Extract (unzip) the download on your computer first, then copy only the single file for your machine, such as the .pes or .jef, onto the USB stick.
3. The file is buried too deep in folders
Many home machines only look at the top level of the USB stick, or one folder down at most. If your design sits in Downloads > Designs > Christmas > PES, the machine may never find it. Copy the file directly onto the root of the stick, outside of any folder, and try again.
4. The USB stick isn't compatible
Machines are fussier about USB sticks than computers are. Things to check:
- Format: Most machines need the stick formatted as FAT32 (sometimes called MS-DOS FAT on a Mac). Large sticks often come formatted as exFAT or NTFS, which many machines can't read.
- Size: Older models may not recognize high-capacity sticks. A small, basic stick is usually the safest choice. Your manual may list a maximum.
- Clutter: Hundreds of files on one stick can slow the machine down or hit a file limit. Keep a dedicated stick with just the designs you're stitching this week.
Reformatting erases the stick, so copy anything you want to keep onto your computer first.
5. The file name is too long or has odd characters
Some older machines can't display long names or names with symbols, accents or extra dots. Rename the file to something short using plain letters and numbers, for example rose01.pes, keeping the original extension.
Mac users: macOS writes hidden files beginning with "._" onto USB sticks. Some machines see these as broken designs. If you see duplicate entries that won't open, the real file is usually the one without the "._" prefix.
6. The design is bigger than your hoop or machine
If the design is larger than the biggest hoop your machine supports, it may appear greyed out, show an error, or refuse to open. A 5x7 inch design won't open on a machine whose largest field is 4x4. Check the design dimensions on the product page against your machine's maximum embroidery area.
Shrinking it on the machine screen isn't always the answer. Most designs only resize safely by about 10–20% before density and small details suffer. For a bigger jump, the design should be properly re-sized or re-digitized for the new dimensions.
7. The download was incomplete or corrupted
A download interrupted halfway can leave a file that looks normal but won't open, or shows 0 KB in size. Delete it, download again, unzip again and copy a fresh copy to the stick. Safely eject the stick from your computer before pulling it out, as yanking it mid-copy is another common cause of corrupted files.
8. The machine has a stitch, colour or software limit
Some entry-level and older machines limit how many stitches or colour changes one design can have, or need a firmware update to read newer file versions. If one particular design won't open but others do, compare its stitch count and colour count with your manual's specs, and check the manufacturer's site for updates.
A quick checklist before you stitch
- Correct format for your machine brand
- File unzipped, single file copied
- Saved at the root of the stick, not in folders
- Stick formatted FAT32 and not overloaded
- Short, plain file name
- Design fits your largest hoop
- Fresh download, stick safely ejected

When the problem is the file itself
Sometimes the file opens fine but it was never made for your machine or size, for example an auto-converted logo from an image that stitches poorly. That's where a properly made file helps. With our custom embroidery digitizing service, your artwork is hand digitized (no auto-conversion) and delivered by email within 12 hours in the formats you need, including EMB, DST, PES, JEF, XXX, VP3, SEW, HUS and more. Pricing is $10 for designs 6 inches or less and $20 for larger, size changes and tweaks after delivery are free, and we re-digitize until it stitches right. You can read how our digitizing service works before ordering.

Quick FAQ
Why does my embroidery design show up in the wrong colours?
DST files don't store thread colours, only colour-change stops, so the machine shows default colours. The stitching is unaffected; just choose your threads at each stop.
Can I rename a DST file to PES so my Brother reads it?
No. Renaming changes the label, not the data inside. The file has to be converted with embroidery software, or you need the original PES version.
My machine reads some designs but not one specific file. Why?
That points to the file: it may be the wrong format, too large for your hoop, over your machine's stitch or colour limit, or corrupted during download. Re-download it and check its size first.
