Locating datasource

,

Hi support,
My data source is a simple excel-sheet.
I want to make a backup.
When editing the App in the “Data” - pane. I can select the table and
I can see Source-name.
I can see the Qualifier.
I can see datasource
I can click view data and see my excel-sheet. (as a sample)
I can click view Source and here I’ll only get “Excel opens an empty sheet”
I can see in “Storage” = a link.
Can I use this link to locate my data?

Thank you.
