## Beschreibung
|
||||
|
||||
CONTENT BEREICH
|
||||
`Get-FileInventory.ps1` durchsucht einen Ordner inklusive aller Unterordner und erstellt eine übersichtliche Dateiliste.
|
||||
|
||||
Erfasst werden:
|
||||
|
||||
- Dateiname
|
||||
- Ordner
|
||||
- vollständiger Pfad
|
||||
- Dateiendung
|
||||
- Größe in Bytes
|
||||
- lesbare Größe, zum Beispiel `1,25 MB`
|
||||
- Erstellungsdatum
|
||||
- Datum der letzten Änderung
|
||||
|
||||
Die Ergebnisse werden im Terminal angezeigt und zusätzlich als CSV-Datei exportiert. Die CSV-Datei kann direkt mit Excel geöffnet werden. Wenn das PowerShell-Modul `ImportExcel` installiert ist, erstellt das Script zusätzlich eine `.xlsx`-Datei.
|
||||
|
||||
## Schnellstart
|
||||
|
||||
Öffne `Get-FileInventory.ps1` und passe oben diese Variable an:
|
||||
|
||||
```powershell
|
||||
$TargetFolder = "C:\Temp"
|
||||
```
|
||||
|
||||
Danach führst du das Script aus:
|
||||
|
||||
```powershell
|
||||
.\Get-FileInventory.ps1
|
||||
```
|
||||
|
||||
Die Exportdateien werden standardmäßig im Unterordner `exports` gespeichert.
|
||||
|
||||
## Nutzung mit Parametern
|
||||
|
||||
Du kannst den zu durchsuchenden Ordner auch direkt beim Start übergeben:
|
||||
|
||||
```powershell
|
||||
.\Get-FileInventory.ps1 -Path "C:\Users\patrick.asmus\Documents"
|
||||
```
|
||||
|
||||
Einen anderen Exportordner gibst du so an:
|
||||
|
||||
```powershell
|
||||
.\Get-FileInventory.ps1 -Path "C:\Temp" -OutputDirectory "C:\Temp\Auswertung"
|
||||
```
|
||||
|
||||
Wenn du nur eine CSV-Datei erzeugen möchtest:
|
||||
|
||||
```powershell
|
||||
.\Get-FileInventory.ps1 -Path "C:\Temp" -NoExcel
|
||||
```
|
||||
|
||||
## Optionaler Excel-Export
|
||||
|
||||
Für den direkten Export in eine `.xlsx`-Datei wird das Modul `ImportExcel` verwendet. Falls du es installieren möchtest, starte PowerShell und führe aus:
|
||||
|
||||
```powershell
|
||||
Install-Module ImportExcel -Scope CurrentUser
|
||||
```
|
||||
|
||||
Danach erzeugt das Script automatisch zusätzlich zur CSV-Datei auch eine Excel-Datei.
|
||||
|
||||
## Hinweise
|
||||
|
||||
- Die Suche läuft rekursiv, also inklusive aller Unterordner.
|
||||
- Versteckte Dateien werden berücksichtigt.
|
||||
- Ordner, auf die PowerShell keinen Zugriff hat, werden übersprungen.
|
||||
- Die CSV nutzt ein Semikolon als Trennzeichen, damit sie in einer deutschen Excel-Umgebung sauber in Spalten geöffnet wird.
|
||||
- Wenn der Exportordner innerhalb des Suchordners liegt, wird er nicht in die Auswertung einbezogen.
