MongoDB wiredTiger Error: collection-*.wt does not appear to be a WiredTiger file (Window10)
@Lizhen, may be Wiredtiger does unclean shutdown. Just go to 'E:\Work_App\MongoDB\bin' and type in command prompt like 

Then run the query in command prompt “mongod --dbpath /data/db –repair”

Suppose that i have installed MongoDB in C:\Program Files\MongoDB\Server\3.2\bin then the query statement will be like that

C:\Program Files\MongoDB\Server\3.2\bin&gt;mongod --dbpath /data/db --repair


As you already said your MongoDB installation path is E:\Work_App_MongoDB\bin. So in your place it would be

E:\Work_App_MongoDB\bin&gt;mongod --dbpath /data/db –repair 


I hope so that it will be help out to you.
