Move files to subfolders if they match in Powershell etc? - powershell

Question

I've googled for a while now but I'm unable to find any solution for this.
So I have a bunch of files in a folder, and in this folder I have subfolders.
I want to move those files to the subfolders if they match any of these.
Like this:
some random text yellow bananas more text.txt -> \yellow bananas
some other text red apples this is text.txt -> \red apples
Example - files:
Propulsion_mål_2020.jpg
Axevalla Vivid Wise As Goop.jpg
Dagens stjärna Cyber Lane.jpg
640px Elian Web heat.jpg
...
Example - directories:
Propulsion
Vivid Wise As
Cyber Lane
Vitruvio
...
Target:
1st file goes to 1st directory
2nd file goes to 2nd directory
3rd file goes to 3rd directory
4th file match no directory and goes nowhere
Is it doable?
Btw, it's possible that more than one subfolder matches the filename. If so, it doesn't matter which subfolder the file is moved to.

here's one way to do the job ... [grin] there is nearly zero error checking or handling, so you may need to add that. nor is there any record of what was done/not-done.
what it does ...
sets the constants
all one of them. [grin]
creates the files & dirs to work with
when you are ready to work with your own data, remove the entire #region/#endregion block.
gets a list of the dirs in the target location
creates a regex OR of the names of those dirs
gets a list of files in the target dir
iterates thru those files
tests for a match of the .BaseName property of each file against the dir name regex from earlier
if YES, creates a full dir name & moves the file
if NO, writes a warning to the warning stream
that is on by default, so you otta see it when such a file is found.
finishes iterating thru the file list
the code ...
$SourceDir = "$env:TEMP\user3764769"
#region >>> create some files & dirs to work with
# when ready to do this for real, remove this entire block
if (-not (Test-Path -LiteralPath $SourceDir))
{
# the $Null suppresses unwanted "what was done" output
$Null = New-Item -Path $SourceDir -ItemType 'Directory' -ErrorAction 'SilentlyContinue'
}
#'

$Null = New-Item -Path $SourceDir -Name $_ -ItemType 'Directory' -ErrorAction 'SilentlyContinue'
}
#endregion >>> create some files & dirs to work with
$DirList = Get-ChildItem -LiteralPath $SourceDir -Directory
# the "|" is what regex uses for `-or`
$RegexDL = $DirList.Name -join '|'
$FileList = Get-ChildItem -LiteralPath $SourceDir -File
foreach ($FL_Item in $FileList)
{
# the matched value is stored in $Matches[0]
if ($FL_Item.BaseName -match $RegexDL)
{
$DirName = $Matches[0]
$FullDirName = Join-Path -Path $SourceDir -ChildPath $DirName
Move-Item -LiteralPath $FL_Item.FullName -Destination $FullDirName
}
else
{
Write-Warning ''
Write-Warning ( 'No matching directory was found for [ {0} ].' -f $FL_Item.Name)
Write-Warning ' The file was not moved.'
}
} # end >>> foreach ($FL_Item in $FileList)
output with one file that does not match any dir in the list ...
