The Export Tile Cache tool in ArcGIS Pro does not indicate .tpk and .tpkx files as invalid file formats for the tool to run.

Workaround

• Refer to the note regarding .tpk files in FAQ: Is there a way to reduce a tile package file size in ArcMap?
• In the Export Tile Cache tool in ArcGIS Pro, attempt to select the .tpk or .tpkx file via the Browse option. The tile package file is not visible, suggesting the tool is unable to run the file.
