Compatibility with YADE branches 1.x - DisableMakeDirectories=true

Current Situation

• When Profile /.../ TargetFileOptions / DisableMakeDirectories = true
  • Behavior in YADE 1.x
    • The transfer fails if the target directory does not exist.
  • Behavior in YADE 2.x
    • The target directory is created if it does not exist.

Desired Behavior

• The transfer should fail if the target directory does not exist.
• No directories should be created automatically.
• Note for documentation purposes (already implemented in previous releases):
  • If the source Selection is set to Recursive:
    • Files in subfolders will still be transferred, potentially overwriting each other in a single directory.
