tl:dr
reasons against ...

• not posh-ish [grin]
  
• script maintenance in general purpose environments
  
• returns a string instead of a fileinfo or dirinfo object
  
• [killer negative] the only OnError action is STOP
  this makes it pretty useless in a general purpose environment without custom error handling.
  
• doesn't REALLY grab anything until you try to use it [thanks to u/da_chicken]
  returns a "FileSystemEnumerableIterator`1" type that has almost no info until you try to use it. plus, it re-gets that info each time you use it.
  

reason for ...

• fast
  100k files on an HDD = 18 seconds for GCI, 5 seconds for SIOD
  [corrected using info pointed out by u/da_chicken]
  100k files on an HDD = 18 seconds for GCI, 0.0005 seconds for SIOD
  

howdy y'all,

a post by ihaxr got me to playing with SIOD for getting files. for giggles, i timed it compared to Get-ChildItem and it's 44k times faster.

yes, forty four thousand.

here's the post [and code] ...

so now i am wondering if anyone has done a cmdlet using that. perhaps something like Get-FileSysItems. tried searching and found nothing, but that only means my search-fu aint up to snuff.

would some kind person please point me to where someone has done the work - and shared it?

i mean, otherwise i would need to write it myself! eeewwww ... [grin]

take care,
lee
