CMS Application - Delivery - Set as current version - Deploy source code - Fatal Error - java io FileNotFoundException Access is denied

On accepting the delivery and setting as current version,we get the error FATAL Unpackaging of sources failed during deployment  java.io.FileNotFoundException:[PATH_OF_THE_FILE] (Access is denied)

On checking the Castlog2 file,you can find the error like

java.io.FileNotFoundException: .....\Thumbs.db (Access is denied)

1. Package and deliver the application
2. Set as current version

1. Check if the sources are already present at the location where you are trying to deploy.Remove all the source codes from the deployment folder path and then accept delivery and set as current version.It is an expected behaviour.
2. If the error is   java.io.FileNotFoundException:  thumbs.db Access is denied
   About Thumbs.db file:It stores graphics, movie, and some document files then generates a preview of the folder contents using a thumbnail cache.These folders are generated automatically by Windows so that folder content doesn't need to be recalculated every time the folder is viewed.Thumbs.db files are stored in each directory that contains thumbnails on Windows systems. The file is created locally among the images, however, preventing system wide use of the data and creating additional data load on removable devices.
   We can ignore these types of files while extraction.To ignore the following files you can use the below regular expression while packaging the code.
   It is mentioned in the below page: Delivery Manager Tool - Information - File Types and folders which can be ignored
