I want to extract a raw file from MongoDB GridFS (it is attached in chats).  
I have searched and find `mongofiles` command.

```auto
root@0e8bbf1e13cb:/# mongofiles -v -d rocketchat_uploads list
2020-11-26T15:06:46.937+0000	using write concern: w='majority', j=false, fsync=false, wtimeout=0

```

fmm… mongofiles list command doesn’t list files.  
Why? am I wrong?

```auto
root@0e8bbf1e13cb:/# mongo
rs0:PRIMARY> use rocketchat
rs0:PRIMARY> show collections
...
...
...
rocketchat_uploads
rocketchat_uploads.chunks
rocketchat_uploads.files
rocketchat_user_data_files
rocketchat_webdav_accounts
system.indexes
system.views
ufsTokens
users
usersSessions
rs0:PRIMARY> db.rocketchat_uploads.find()
(Appear files list)

```
