Rsync cleverly deletes a large number of small files

Rsync uses the replacement principle to quickly delete large numbers of files.

1. Use rsync to empty the directory

<1> Create an empty directory first

mkdir Blank

<2> Delete target Directory

rsync--delete-before-d-a-h-v--progress--stats/blank./destination

or rsync--delete-before-d blank/destination

2,-delete-before before transmission to delete operations

-progress Transmission during transmission

-a archive that means transferring files recursively

-H keep hard-linked files

-V Verbose mode

-stats gives the transfer status of some files

-D
