File filter in Nifi UnpackContent
I have a tar file with .csv, .xml, and .txt files that I want to unpack using the UnpackContent processor. Can I specify all three file types in the file filter?

The file filter property of the unpackContent processor takes a java regular expression and can be used when unpacking tar or zip file.
In your unpackContent processor, set the "Packaging format" to either "ZIP" or "TAR" based on what package format is used by your source file.
The set a java regular expression such as below to extract only files within that package where the filename ends with the .csv, .txt, or .xml extensions:
.*\.(txt|xml|csv)
Hope this helps,
Matt
