Initially it seems like an easy request, "can I have a copy of the images from this folder including all the sub-folders", and then you remember Sitecore stores all the images in the DB so those folders that they're in aren't real file folders for you to copy and paste from. Hopefully you check the admin for an export button only to discover that the only download button for an image is on the individual image, not the folder. Being a developer faced with the prospect of having to click a download button on an unknown number of images, you do what every good developer does and try and find an alternative.

The good news is your in luck, there is a way and I'm going to tell you it.

Sitecore Powershell Extensions

Not only is Sitecore Powershell extensions a great way of writing scripts to interact with your Sitecore DB without having to do code releases. It also comes with the exact script you need!

First head over to the Sitecore Marketplace and download the correct package for your Sitecore version. https://marketplace.sitecore.net/en/Modules/Sitecore_PowerShell_console.aspx

Installation is simple, you just install the package, no config changes needed.

Now go to the media library and right click the folder you want to export. In the context menu, select scripts and then download.

Just like that, a dialogue appears asking you if you want to download the zip it just created. Click download and you will have all the images.

They will even be organized with the correct folders inside.

I recently needed to run a script on a block of Sitecore content in invert the selection of a checklist and multilist. As I couldn't find any example of how to do this at the time, I thought I'd share what I wrote.

Get-ChildItem -r -Path "master:\content\Home" -Language * | ForEach-Object {

This line is getting the child items from the home node in the master db. The -r specified that it should be recursive and the -Language * specifies to include all languages. The results are then piped to a for each loop.

if ($_.PSobject.Properties.name -match "Tier") {

The field I needed to update was called Tier, as this was included in multiple templates I checked that the object included a field called Tier, rather than checking the template types.

[String[]]$tiers = $_.Tier -split "\|"

List fields in Sitecore get stored as a pipe separated list of the item Id's for the selected items. In order to do a comparison in Powershell I needed to turn the string back into an array using the split command. Notice the backslash that is needed before the pipe.

$_.Editing.BeginEdit()

To edit an item you need to begin an edit

$newtiers = Get-ChildItem 'master:\content\Components\Lookups\Tiers\' | Where-Object { $tiers -notcontains $_.Id }

This is where we get the new list of tiers to set as the selected ones for the item. The Get-ChildItem command is retrieving the original options that could be selected and the where-object statement is then excluding the ones that are in the $tiers array we just made.

$_.Tier = $newtiers.Id -join "|"

To save the new list we need to convert the results of the query into a pipe separated list using a join.

$_.Editing.EndEdit() } }

End the editing to save and close the the if and loop statements.
