• 64GB ≈ 58–60 GB usable

Frequently Asked Questions

Q: How do I submit my custom logo for the USB flash drives?

A: You can send your logo file (JPG, JPEG, GIF, PNG, or BMP format, up to 5MB) through the seller's customer service chat either before or at the time of payment. Laser engraving is free of charge. If you require a full-color printed logo, please contact customer service to arrange the additional color print fee.

Q: Why does my computer show less storage than the labeled capacity?

A: This is completely normal. Flash memory manufacturers measure capacity in decimal (1GB = 1,000MB), while operating systems use binary (1GB = 1,024MB). This means a 32GB drive will show approximately 28–30GB of usable space on your computer — the drive is working correctly.

Q: Are these USB flash drives compatible with Mac and Linux systems?

A: These drives are confirmed compatible with Windows 98/ME/2000/XP/Vista/7/8 and later. As standard USB 2.0 mass storage devices, they are also generally compatible with macOS and Linux systems that support USB mass storage — no additional drivers are required.

Q: What is the minimum order for custom logo USB flash drives?

A: Each listing covers a pack of 20 USB flash drives. This is ideal for small business promotions, events, or bulk gifting. For larger quantities, please contact customer service to discuss options.
