Often, after implementing a new system or application on BizTalk, we need to provide a report to management of how many files were processed.

If you keep an archive of all files in or out, you can use that with a simple PowerShell to accomplish the report. Here’s an example I found:

PowerShell Example 1 – Files by Date

<pre>
$count = @{}
$size  = @{}

get-childitem d:\BizTalk\MyApp\Archive\EDI850Order\*.txt |
 foreach {
           $date = $_.lastwritetime.tostring('dd-MMM')
           $count[$date]++
           $size[$date] += $_.length
         }
 $count.keys |
  sort|
  foreach {
           [PSCustomObject]@{
            Date = $_
            'Number of files' = $Count[$_]
            Size = $Size[$_]
           } 
         } | format-table -AutoSize
</pre>

Sample Results of Above Powershell

<pre>
Date   Number of files   Size
----   ---------------   ----
08-Sep              14  37263
11-Sep              19  53761
12-Sep               7  26984
13-Sep              45 147575
14-Sep              44 154050
</pre>

Example 2 – Multiple Folders – Files by App and Date

<pre>

$items |
 foreach {
           $posFirstSlash  = $_.fullname.indexOf("\") 
           $posSecondSlash = $_.fullname.indexOf("\", $posFirstSlash+1) 
           $posThirdSlash  = $_.fullname.indexOf("\", $posSecondSlash+1) 
           $lenApp = $posThirdSlash - $posSecondSlash - 1 
           # Write-Host $app $posSecondSlash $posThirdSlash $_.fullname 
           $date = $_.lastwritetime.tostring('yyyy-MMM-dd')
           $app = $_.fullname.substring($posSecondSlash+1,$lenApp)
           $key = $app+" "+$date
           $count[$key]++
           $size[$key] += $_.length
         }

 $count.keys |
  sort|
  foreach {
           [PSCustomObject]@{
            App_Date = $_
            'Number of files' = $Count[$_]
            Size = $Size[$_]
           } 
         } | format-table -AutoSize
</pre>
