INPUTS



OUTPUTS



NOTES





When using the -Recurse parameter, the md5 hash of each descendent file has to be calculated, in order for

comparison against all other descendent files' md5 hash.

Therefore, if using Get-Duplicate with the -Recurse parameter on a folder containing many large descendent

files,

it is to be expected that the Cmdlet might take several seconds to several minutes to complete, depending on

the

size of those files.
