PowerShell to filter file size

I am trying to write a script using PowerShell to get file size 0kb as mentioned below 

$FileExists1 = 'C:\Users\iskandar\Desktop\TEST\*\test0700.txt'

IF (Test-Path $FileExists1) {
    If ((Get-Item $FileExists1).length -gt 0kb) {
      Write-Output "All file size is good!"
    }

Else {
      Write-Output " There is a file with 0KB, Please inform support staff"
    }
}

if there is multiple folder with multiple file, the script not filter the 0KB file.

for example : lets say I have 30 files and only one file with 0KB, when I run those script, it shows "All file size is good!".

Can anyone advice?. Thank you

Though Esperento57 has provided a working solution, let's see what is wrong in the original code.

The problem happens as you are hit by object mismatch. Multiple objects have same attributes that contain different things.

For a single file, Get-Item will return a FileInfo object that contains file's size in its .Length attribute.

For multiple files, Get-Item will return an array of FileInfo objects. Its .Length attribute contains the length of the array itself. Thus the statement

If ((Get-Item $FileExists1).length -gt 0kb) {

actually is processed as pseudocode

if ($FileExists1-the-array contains more than 0 elements) {

try this:

$files=gci "C:\Users\iskandar\Desktop\TEST" -file -Recurse | where Length -le 0Kb | select -First 1

if ($files.Count -gt 0)
{
    "There is a file with 0KB, Please inform support staff"
}
else
{
    "All file size is good!"
}
