This page is edited from the 1cmdfaq.txt faq-file contained in my tscmd.zip command line interface (CLI) collection. That zipped file has much additional material, including a number of detached .cmd script files. It is recommended that you also get the zipped version as a companion.

83} How to archive files with a rotation of five latest generations?

I would like to archive some files periodically but only keep the last five iterations. The directories would ideally have date names. I know how to get a date into a directory name but I'm having a bit of trouble trying to figure out how to delete the oldest directory.

Such a backup rotation uses moves or renames. Below is the logic. The commands (e.g. zipping or whatever) are easily written once the simple logic sinks in:
  archive4 --> archive5
  archive3 --> archive4
  archive2 --> archive3
  archive1 --> archive2
  delete archive1
  Do the new archiving to archive1 (optionally with dates)
