I went to the F-Droid app on my phone and searched for "simple text editor"

F-Droid came up with the "Simple Text Editor by Maxim Starkov" version 1.24.0

That installed on my Android 12 Galaxy A32 5G

I allowed it to access photos & media

And it opened to "newfile.txt" saying "Type Something Here"

I entered "this is a test" and hit the three dots and then save

It asked me where to put the file (defaulting to "Downloads")

Instead I put it to the external sdcard, folder 0001, subfolder txt

That seemed to have worked

In Settings, there are useful options which default to

[_]Open last

{To open last edited file}

[x]Show Last Edited Files

{Show last edited files in options menu}

[_]Autosaving

{Automatically save currently editing file when window is closed}

[x]Alternative File Paths

{Allow assigning alternative addresses for files if no file system permissions granted.}

Encoding = (o)UTF-8

(many other encoding options existed)

Line Delimiters = (o)default

(UNIX/Windows/Mac line-ending options existed)

SAVE TO TXT:

The only option I changed was I turned autosaving on.

Then I used a file manager to look for the file it had saved.

One of the options to edit it was the "Simple Text Editor" by Maxim Starkov.

That worked.

OPEN WITH SHORTCUT:

Then I used the SimpleMobileTools FileManager to create a desktop shortcut to the newfile.txt file.

When I tapped that desktop shortcut from the homescreen, a dialog came up asking me which program I wanted to use to edit the text file.

One of the options to edit it was the "Simple Text Editor" by Maxim Starkov.

That worked.

RANDOM TXT FILE:

Then I used the MiX FileManager to create a foo.txt text file on the external sd card in the 0001 folder, and in the txt subfolder.

In MiX FileManager I tapped on that foo.txt file and up came an "Open with" selection which included the newly added "Simple Text Editor" by Maxim Starkov.

That worked.

TEXT FILE COPIED FROM WINDOWS:

Then I copied a text file named snafu.txt from Windows over to the external sdcard 0001/txt foder.

Using the Android FileManager I tapped on that snafu.txt file.

It asked how I wanted to treat that file (I selected "text").

Up came an "Open with" selection which did NOT contain the option for the "Simple Text Editor" by Maxim Starkov.

Instead I selected the MK File Manager text editor (mathewkor)

That worked (but it failed to open in the right editor).

But when I used the "My Files" filemanager, it worked!

EXISTING TEXT FILE

But when I tapped on an existing text file that was created previously, the "Simple Text Editor" by Maxim Starkov went through all the motions as above, but it would not write the file for some reason.

The error is "Cannot write file"

In conclusion, it worked almost perfectly.

When I tapped on the file in almost every file editor, an "Open with set of options came up, almost all of which contained the "Simple Text Editor" by Maxim Starkov.

When I created a homescreen shortcut to the text file, an "Open With" set of options came up containing the "Simple Text Editor" by Maxim Starkov.

When I copied a text file from Windows, the action was the same as the above, which is a good thing.

The bad news...

Two things failed:

When I tap on the text file in some file managers, the Simple Text Editor by Maxim Starkov does NOT show up.

When I tap on old text files, even when the Simple Text Editor by Maxim Starkov does show up, it sometimes can NOT write the file.

Dunno why.

I think what I'll do is copy all the existing files that can't be overwritten for some reason, and then try to start fresh.

Thanks for the advice of using this FOSS "Simple Text Editor" by Maxim Starkov (aka MaxiStar).
