FileID Does Not Match FileHeader


This error is usually caused by two things:

  1. The file you selected is of a differentformat than what is selected in the File Format drop down in the Configuration window.
  2. A .yxdb file you are using as an input has become corrupt.

Other causes can be found here:https://community.alteryx.com/t5/Alteryx-Knowledge-Base/Error-FileID-does-not-match-in-the-FileHeade...

Although extremely rare, if a .yxdb file becoming corrupt is the culprit (one cause is a network connection dropping in the middle of writing the file), you may have a quick and simple way to resolve this potentially stomach-dropping issue:

  1. Open up Windows Explorer and navigate to the file.
  2. Right-click on the file and choose Properties.
  3. Click on the Previous Versions tab.

If you're lucky, there isat least one option of the file that you can revert back to you, hopefully allowing you to avert disaster. Obviously, this doesn't just work with Alteryx files, so perhaps this knowledge will come in handy with other files.

Thanks for reading!
