How to delete files in destination folder that are already present in source folder

  • 772

I got two folders, a source S with files (and subfolders and so on):

  • a.txt
  • b.txt
  • c.txt
  • ...

and a destination folder D with files:

  • a.txt
  • b.txt
  • b1.txt
  • c.txt
  • c2.txt
  • ...

and I want to delete all files in D that are already present in S, so that D contains just files that are not present in S.

Any ideas, how I can achieve this with standard tools (rsync, robocopy, ...)?

P.S.: In real world S is about 800GB and contains 4*10^6 files and D is about 802GB and contains 4.1X10^6 file spread across the whole subtree.

P.P.S.: Yes, I can do some programming (bash, batch, ...), but I don't want to reinvent the wheel and want to check the (possibly) obvious first.

bash rsync batch robocopy xcopy
