Sort photos by EXIF date taken in a folder structure (WINDOWS).

Introduction

My camera photos on my phone all end up in one big folder. I wanted to sort them by date taken in a simple format year-month format, YYYY-MM. I tried the application PhotoMove, but unfortunately, this simple requirement is only available with the PRO version, so instead, I've asked ChatGPT to create a PowerShell script for me.

Usage:

  1. Download the Windows version from exif tool and unzip it into a folder. Make sure that the name is exiftool.exe (in my case, it had a weird name exiftool(-k).exe so rename it if that's the case).
  2. Save the PowerShell script you can find below in the same folder.
  3. Open a PowerShell window (WIN+R and enter powershell)
  4. Run the script ./sort.ps1

Create a new Docker volume and fill it with local data

Create Docker volume

When moving from a local development environment to the cloud, e.g. Docker swarm or Kubernetes, you often need a way to access local files. However, in the cloud your local file system cannot be accessed anymore, so you need a way to copy your local files to a volume and mount that instead. This is the purpose of the script. You supply it with the volume name (e.g. schemas) and the local folder containing the schemas, e.g. ../../schemas, and a schemas volume is created, containing all data that is copied into the container.

./create_volume.sh schemas ../../schemas
