Check single file size

[Cathy]

I am just getting started in powershell, (have been using DOS batch files so
far.)

I would like some assistance to write a simple batch file to check the file
size of a specific file. The file is not allowed to be more than 5gb.

The steps are therefore

1. Set Max_file_size = 5gb
2. Set warning_level = 10%
3. Set Warning_File_size = Max_file_size - (Max_file_size * warning_level)
3. Check file_size
4. if file_size > Warning_file_size
Echo File is too large
endif

If anybody could help me get this scripted I would really appreciate it

regards
C

Steps 1–3 always result in a warning file size of 4.5 GB. I've condensed
these steps; I leave it to the reader to expand them if desired.

I have not included any kind of error-checking. It is written as a
script, though you could instead make it a function.


param($File_Path)
$Warning_File_Size = 4.5GB
$File = Get-Item -Path $File_Path
if ($File.Length -gt $Warning_File_Size)
{
Write-Host "File is too large"
}

Thanks for the response. Really appreciate this

I did this to allow me to change the warning percentage to suit.

I will look into this once I become more comfortable in Powershell

Thanks again for your help
