I am starting to use GridFS within a Meteor app. I have set up the file collection \"assetFiles\" with a GridFS storage adapter like this :
AssetCollection = new
you need to change the prefix to attach to the right collection.
$ mongofiles --help .... --prefix= GridFS prefix to use (default is 'fs')`
eg.
mongofiles --port 3001 -d meteor --prefix 'cfs_gridfs.assetFiles' list
hope this helps! accept please thanks!
