As a collaborator of a folder in Box, you have certain permissions to access a folder and all of its subfolders. With this structure, your path to retrieve files will be different than a regular user of the account.
For a regular user, suppose the path to retrieve a file would look like this:
/parent/folder1/folder2/folder3/test-file.pdf
A collaborator that only has access to "folder2" will retrieve the file with this path:
/folder2/folder3/test-file.pdf
