You need to get the ID of the folder this can be done with the list command. If there are a lot of object you will need to use the query option to narrow it down. If you want a list of objects in the root you can use 'root' as the ID e.g.,

./gdrive list --query " 'root' in parents"
or

./gdrive list --query " 'IdOfTheParentFolder' in parents"

I also need this.

I must be a complete dumbass

parent_folder (parent_id)
└─child_folder (child_id)

So if I want to get the content of the child_folder, is the command:

gdrive list --query "child_id"`

?

i tried both
gdrive list --query "child_id"`

and

gdrive list --query "parent_id"`

Getting error 400 on both

@taewookim Are you using the folder name for the parent_id, or are you using the actual ID hash? Also, you need to include the "in parents" part in your query. For example:

./gdrive list --query " 'child_id' in parents"
