Get rows with greatest value based on value in first column

Hello all,

I did not know anything about Excel but the most basic functions.

I want only the rows with the greatest value (3rd column) per user (1st column).

Here's a sample of the data:

user1 file1 5
user1 file2 2
user2 file1 244
user2 file2 104
user2 file4 1
user2 file3 1
user3 file2 390
user3 file1 193
user3 file3 2
user3 file4 2
user4 file1 243
user4 file2 85
user5 file2 136
user5 file1 123
user5 file4 17
user5 file3 8


Desired output:
user1 file1 5
user2 file1 244
user3 file2 390
user4 file1 243
user5 file2 136

Thanks for your help!
