Is it possible to have the charge density files generated within a specific folder when performing an RT-TDDFT calculation? #8151

Background

When performing RT-TDDFT calculations, it is sometimes necessary to examine the charge density, which results in the generation of a large number of files with the .cube extension. Currently, all these charge density files are created directly within the OUT directory; as a result, other files often end up buried far down the list, as shown in the image.

Describe the solution you'd like

It would be ideal to keep these files in a single folder when performing RT-TDDFT calculations, similar to how the wave function files are handled.
