How do I find images based on their numbers in the Excel file?

Question

I have 1,015 images in a folder and this image is classified into seven types and these types are categories of medical diagnoses of skin cancer, and the same images are classified in the Excel file by number (the number of each picture corresponds to the type of diagnosis of this image). Clearly, each image has a specific number corresponding to the diagnostic type, my question is how to sort these images in the folder in groups so that each group of images have the same diagnosis.

Answer 1

You can try an approch like the following in powershell It can certainly be optimized, but I wanted it simple to understand with 2 steps : - The first one : creation of the target tree according to your input file (.csv) - The second one : moving image files in the corresponding subdirectories)

#The process : 
$BasedImages = "\\path\to\ImagesDirectory"
$csvfile = "\\path\to\Inputcsvfile.csv"

#Gather all subfolders in the Images Directory (only first level) and put the name of these folder in a var. The only property useful for later use is the Directory name. Useless to gather all properties 
$ExistingSubDir = Get-ChildItem -Path $BasedImages -Directory | Select-Object -Property name

# Gather unique diagnosis in the input file and put in a var. The only useful property in the dx property for a later use. Useless to collect more info. 
$UniqueDiagnosis = Import-Csv -Path $csvfile | Select-Object -property dx -Unique

# gather all images files FullName in the Images Directory and put in a var. it seems that only  Name,DirectoryName, FullName properties will be usefull for later use
$AllImagesFiles = Get-ChildItem -Path $BasedImages -File | Select-Object -Property Name, DirectoryName FullName

# now First Step : build a Tree with  subfolders named by the unique Diagnosis name. 
foreach ($Diagnosis in $UniqueDiagnosis)
    { 
    # search if a diagnosis dir name (dx field in the input .csv file) exist in the ImageDirectory and put the result in a var
    if ($ExistingSubDir -contains $Diagnosis) 
        { 
        Write-Host "$ExistingSubDir is still existing, no action at this step" -ForegroundColor Green 
        }
    else
        {
        New-Item -Path $BasedImages -Name $Diagnosis -ItemType Directory
        Write-Host "a sub-directory named $Diagnosis has been created in the folder $BasedImages" -ForegroundColor Yellow
        }
    }

# At this step, you'll have some sub directories named with the name of all diagnosis (fied dx in the input file)
# Now Step 2 Time to move the files in the root folder
foreach ($image in $AllImagesFiles)
    { 
    $TargetSubDir = Get-Item -Path $($image.fullName)
    Move-Item -Path $($Image.FullName) -Destination ( Join-Path -Path (Split-Path -Path $($Image.DirectoryName) -Parent) -ChildPath $TargetSubDir)
    Write-Host "the image named $($image.name) has been moved to the sud directory $TargetSubDir" -ForegroundColor Green
    }

Careful, i haven't completly tested the code, use with caution.
