A while ago I was having some issues with SSIS and moving files. There was a hidden file called thumbs.db
When SSIS was running the move file task it would fail because it can’t place duplicate files in the same location. The thumbs.db file was the problem. Even though it was hidden as a windows file, SSIS still saw it and wanted to move it.
This is where limiting SSIS to a specific file type saves you from this problem.
To do this you filter on the Foreach Loop Container. You select the container and then you click on Properties.
In the Properties right at the top you shall see FileSpec. There you can set it to the file type you would like to filter/limit for.
And that’s how you limit SSIS to a specific file type!
