    Data Engine Error: 4: The process cannot access the file because it is being used by another process

      Hello,

       

      About a week ago I started experiencing the following error on a very regular basis:

      Tableau Data Engine Error: 4: The process cannot access the file because it is being used by another process. - DataFile::DataFile(path="C:\Users\NA433~1.BON\AppData\Local\Temp\tmp6F0D.tmp", writable=true) Could not create file handle.

       

      I encounter this error in different sort of situations:

      - when trying to add a text file datasource (the file is about 70K rows / 10 columns)

      - when trying to extract a custom sql datasource

      - when trying to refresh an existing datasource based on a csv (very small datasource 2k rows / 20 columns)

       

      I have sometimes been able to find a workaround by reducing the volume of the datasource i am trying to create.

       

      I am still sceptical about what is causing this error though as:

      - people of my team can create those datasource without encountering this error

      - I used to be able to create this kind of datasources and handle much larger datasets (5M-10M rows / 20 columns) two weeks ago.

       

      Is anyone able to help?

      thanks a lot

       

      Nicolas
