You can recognize the meaning from the context. In nature (forest, mountain), it is a path. On the computer (file, directory), it is the storage location. In a moral or philosophical context (life, virtue), it is a metaphor.
Der Pfad führte steil den Berg hinauf.
The path led steeply up the mountain.
When referring to a path in nature, 'Pfad' (path) is often combined with verbs such as 'folgen' (to follow), 'entlanggehen' (to walk along), or 'verlassen' (to leave). Common adjectives are 'schmal' (narrow), 'steil' (steep), or 'versteckt' (hidden).
Wir sind einem schmalen Pfad durch das Unterholz gefolgt.
We followed a narrow path through the undergrowth.
The computer meaning is a metaphor. The 'Pfad' (path) describes the exact 'way' to a file through the hierarchical folder structure, like a signpost in the real world.
Der Systemadministrator muss den vollständigen Pfad kennen.
The system administrator needs to know the full path.
The figurative meaning is often used in fixed expressions, for example 'den Pfad der Tugend verlassen' (to leave the path of virtue), 'neue Pfade beschreiten' (to break new ground), or 'auf krummen Pfaden wandeln' (to walk crooked paths).
Mit diesem Projekt beschreiten wir völlig neue Pfade.
With this project, we are breaking completely new ground.
direction
'die Richtung' and 'der Pfad' can both have to do with a way or route. 'Richtung' says where someone is going, driving, or looking. So it is more about orientation or the destination. 'Pfad', on the other hand, is a specific narrow path, often in nature. Figuratively, 'Pfad' can also mean a way of life or an approach, while 'Richtung' more often shows whether something is moving in a particular direction of development. They can be confused because both are connected with movement. Memory tip: 'die Richtung' says where to, while 'der Pfad' is the path itself.

Der Pfad durch den Wald war schmal und nach dem Regen sehr rutschig.
The path through the forest was narrow and very slippery after the rain.
Nach der Kreuzung wusste Tom nicht mehr, in welche Richtung er gehen sollte.
After the intersection, Tom no longer knew which direction he should go.
