Test-Path/Get-Item cannot find/return info on files that are locked like
|
|
C:\pagefile.sys. These 2 functions are designed to work with these files and
|
|
provide similar functionality with the normal cmdlets with as minimal overhead
|
|
as possible. They work by using Get-ChildItem with a filter and return the
|
|
result from that.
