The more things in your Drive, the trickier it can be to find things (especially if they are not organised or you are not using folders).

The SEARCH feature in Drive is really helpful.

1) You can type into the search box to try to find something

2) There are also ways to make your search more specific by choosing what kind of file it is or who owns it.

Check out the GIF below for some ideas and then try it out yourself.
