USB 3. 0 — A thin, rectangular slot that’s about 3/4 of an inch (a little under two centimeters) wide. You should see a chunk of plastic in the upper half of this slot. USB 3. 0 slots are found on the majority of Windows computers and on most Mac computers manufactured prior to 2016. USB-C — A thin, oval slot that’s about 1/2 of an inch (a little over a centimeter) wide. These are most commonly found on MacBook and MacBook Pro computers, though some Windows laptops also have USB-C ports. If your computer has both types of port, you’re free to use whichever port you like depending on your USB flash drive type.

If the connector is rectangular and has a piece of plastic taking up part of the connector, you have a USB 3. 0 flash drive. If the connector is oval and has no piece of plastic inside of it, you have a USB-C flash drive.

This is most common on MacBooks and MacBook Pros from 2016 and up, though some Windows computers also have only USB-C ports.

USB-C flash drives can be inserted either way. If you’re using a USB-C adapter, you’ll plug your USB flash drive into a USB 3. 9 slot in the adapter instead.

You can quickly clear a drive of files by dragging the files in question into your computer’s Recycle Bin (Windows) or Trash (Mac).

If you want to store files larger than 4 gigabytes, select exFAT (Windows) or ExFAT (Mac). Flash drives formatted for Windows-only use aren’t compatible with Mac computers, and vice versa. Formatting the flash drive for a compatible format will fix this issue.
