@cvp You are right the path has changed. It looks like the path for external files is "/private/var/mobile/Containers/Data/Application/37E6A0DC-0618-4E14-9AD2-75E03BA90884/Documents/Mappe.xlsx"

The path of the Pythonista Files is Path='.../6ABBAC2F-5C86-4FDE-9028-6379CF4EE774/...'

That solved my problem. Thank you very much for your continued support.

@cvp The same errormessage "[Errno 2] No such file or directory"

@pvg No, it's not o.k.. I make the following steps:

1. Save the Excelfile with Excel on "Auf meinem iPad"
2. Change to Pythonista
3. Under "EXTERNAL FILES" choose "Open..." then "Folder..." then "Auf meinem iPad". The file is not there
4. I chosse the subdirectory "Excel" an there i found the file
5. When i choose the subdirectory, i see the name at the top "Documents"
6. I choose the following pathes:
   a. path ='/private/var/mobile/Containers/Shared/AppGroup/6ABBAC2F-5C86-4FDE-9028-6379CF4EE774/File Provider Storage/Mappe.xlsx
   b. path ='/private/var/mobile/Containers/Shared/AppGroup/6ABBAC2F-5C86-4FDE-9028-6379CF4EE774/File Provider Storage/Excel/Mappe.xlsx'
   c. path ='/private/var/mobile/Containers/Shared/AppGroup/6ABBAC2F-5C86-4FDE-9028-6379CF4EE774/File Provider Storage/Documents/Mappe.xlsx'
   d. path ='/private/var/mobile/Containers/Shared/AppGroup/6ABBAC2F-5C86-4FDE-9028-6379CF4EE774/Excel/Mappe.xlsx
   e. path ='/private/var/mobile/Containers/Shared/AppGroup/6ABBAC2F-5C86-4FDE-9028-6379CF4EE774/Documents/Mappe.xlsx

but when i start the script the command "with open(path,mode='rb') as fil: " >> [Errno 2] No such file or directory

My ios Version ist 13.3.1
My Pythonista Version v 3.3 (330025)

@cvp In your last screenshot you ask me if i open "EXTERNAL FILES" an open "Folder". Yes, when i do this, i see the file which i will open and i can open the file with Excel in the "Pythonista App"

@cvp My mistake. The screenshot is not there. Sorry
I see i have to wait 180 seconds

@cvp I make some other test to open the file like your documentation. I have make a screenshot of my situation. I hope the screenshot will be shown. The script can't open the file.

@cvp Thx for your help.
The status now is:

1. I see under "EXTERNAL FILES" "File Provider Storage"
2. I see the files , but i can't open the files with a Pythonista-Script
3. Now the files which i will open are in the folder "..../Pythonista3/Documents" and this is sufficient

I wish you a few nice days in your holiday

@cvp Thx for your answers even thought your in holiday. I have saved my file in "Auf meinem iPad" and it looks like your screenshot. But their is no directory "File Provider Storage"

When i run the code:
import os
path = '/private/var/mobile/Containers/Shared/AppGroup/6ABBAC2F-5C86-4FDE-9028-6379CF4EE774/'
os.chdir(path)
print (os.listdir())

there are only this files/directories
['.com.apple.mobile_container_manager.metadata.plist', 'Library', 'Pythonista3']

@cvp I use the last version (v 3.3 (330025)) from the App Store

@mikael, thanks for your quick answer.
I save the file "mappe.xlsx" with the App "Dateien-App" in the folder "Pythonista 3", but in the folder:
"/private/var/mobile/Containers/Shared/AppGroup/6ABBAC2F-5C86-4FDE-9028-6379CF436465/Pythonista3/Documents/"
are only folders or file with ending *.py.

or are there other ways to share the file?
