Hi @Paudek148
This describes the problem you've encountered: Troubleshooting combining files
When you combine files using the folder connector, all the files in the folder and its subfolders are processed the same way, and the results are then combined. The way the files are processed is determined by the example file you select. For example, if you select an Excel file and choose a table called "Table1", then all the files will be treated as Excel files that contain a table called "Table1".
To ensure that combining the files works properly, make sure that all the files in the folder and its subfolders have the same file format and structure. If you need to exclude some of the files, first select Transform data instead of Combine and filter the table of files in the Power Query Editor before combining.
You've selected a name (of a table), not present or named differently in one or more files.
I hope this is helpful
