Android Question Delete file from SD card

[strupp01]

I back up and import files to and from an SD card on my tablet. Thanks to help and a sample program from e.g. DonManfred now also works everything.
However, there are problems when deleting files on the SD card. I read a list of all files from the SD card and then I want to delete them. I do the deletion with the command

OK = File.Delete ("/ storage /" & Storage.Root.Name & "/ Sicherheit_Mein_Haushaltsbuch", Temp.trim)

The Storage.Root.Name also corresponds to the name of the SD card. The file name is stored correctly in Temp.
As a result of OK, I always get False. The file is also not deleted. No error message is issued either.
I cannot find an example for deleting files from an SD card on the Internet.
What am I doing wrong? Is the delete command the right one? Who might have a sample program for deleting a file from SD card and can set this.

Is it a real external sdcard or is it the internal sdcard?
If internal then you need to use file.dirrrootexternal + subpath

If external SDCard then you need to use the external storage class.

It is a real external SD card. What I don't understand is how I have to use an external storage class. Can you find something about this on the Internet?

Here is the link in this forum:

ExternalStorage - Access SD cards and USB sticks

Before we start: External storage means a real sd card or a connected mass storage USB device. This class can also be used to access the secondary storage (File.DirRootExternal). This becomes relevant with newer versions of Android that restrict direct access. It has nothing to do with runtime...

I saw the example from @Erel. Unfortunately, there is no example here for deleting a file on a real SD card. Since I can't get any further and the files only have to be deleted once a month, I will do this by hand until an example appears in the forum.
Thanks to @DonManfred and @Mahares for your contributions.

Start with the ExternalStorage example. Once you get the relevant ExternalFile object you can delete it with Storage.DeleteFile.
