Capitalization Tip: File Formats

👉 Most of the time, use all caps for file formats:

“Discussing GIFs out loud is now against office rules. The last argument over pronunciation ended in two black eyes and a broken toe.”

"I forgot to attach the PDF!"

👉 But use lowercase when writing them as extensions:

“Look for the .docx extension on the file name.”

“Maybe downloading Virus.exe was a mistake.”
