SDL auto reading files from a folder

Dears , 

We would like to use SDL in auto reading files copied in the project folder , so for ex:  the project folder called Complaints  , we will place some .docx files , .pdf files in the 'en-US' subfolder under the main project folder 'Complaints' ..

 

However when we place a file there , we can't see it under the project when opening SDL ,  Can you please advise on how to see files dropped in a a specific folder on a server so translators can view new comming documents 

 

Thanks
