Delphi 10 Seattle and up try “recover” unchanged files in the `$(BDS)` tree

Every now – after some period of inactivity – I get an error like this when not having changed the file at all:

---------------------------
Error
---------------------------
Cannot create file "C:\Program Files (x86)\Embarcadero\Studio\18.0\Source\DUnit\src\__recovery\GUITestRunner.pas". Het systeem kan het opgegeven pad niet vinden.

This has been present since ever since Delphi 10 Seattle introduced the “recovery” feature on unchanged files in a read-only directory tree like for instance $(BDS).

It assumes the __recovery subdirectory has been created (which it cannot, but never raised an error about), then barfs when it cannot find the directory.

This is a classic example of “nice idea, bad execution, not caught by thinking through all the test cases”.

I think one of the roles played, is that cursor movements are part of the undo/redo stack. My suspicion is that this raises a “changed” flag, where in fact the file is unmodified.

Het systeem kan het opgegeven pad niet vinden. is the Dutch version of ERROR_PATH_NOT_FOUND error code 0x03 English The system cannot find the path specified.
