Post #17 of our Build Flows Faster series covering our new utility actions for Power Automate. Today’s lesson is about obtaining a file extension from a filename in Power Automate.

Our utility actions are targeted at helping you build flows more quickly with less complexity, and they brilliantly only use 0.05 actions from your Encodian Flowr and Vertr subscription allowance. For example, under a standard plan that permits 500 actions per month (uses), you could use the utility actions 10,000 times!

Introducing the ‘Get File Extension’ Utility Action

Our ‘Get File Extension‘ utility action for Power Automate obtains the file extension as a string value from the filename string value provided. In simple terms, the action returns the text located after the last ‘.’ found within the string value provided, thus ‘this.is.an.example.value‘ would return ‘value‘.
