Folder Enhancer

The VIESUS Folder Enhancer is a Windows desktop application that watches hotfolders and automatically enhances images and PDFs as they arrive — no command line required.

The VIESUS Folder Enhancer is a Windows GUI application built on top of the Image Enhancement CLI and the PDF Enhancer CLI. It watches one or more hotfolders — when a file lands in a watched folder, the Folder Enhancer automatically enhances it and writes the result to a configured destination folder.

Because it drives both underlying CLIs, the Folder Enhancer handles both images (JPEG, TIFF, PNG, …) and PDF documents with embedded images.

The main window lists each configured hotfolder and shows live processing status in the operation log.

How hotfolders work

Each hotfolder is an independent processing channel with its own configuration:

Setting	Description
Source folder	The folder to watch for incoming files
Destination folder	Where enhanced output files are written
Enhancement parameters	A viesusini.json configuration applied to every file in this hotfolder
File type	Images, PDFs, or both

Each hotfolder is created and edited from the Define Hotfolder dialog, where you set the source and destination folders, the viesusini.json settings file, the input type (images or PDF), and options such as trigger files, batch size, and how to handle unsupported files.

The Define Hotfolder dialog — source, destination, and the per-hotfolder settings file and input type.

You can define as many hotfolders as needed — for example one tuned for portrait photos, another for product images, and a third for PDF documents, all running simultaneously with different parameters.

When a file appears in a source folder, the Folder Enhancer:

1. Detects the new file
2. Applies the enhancement settings configured for that hotfolder
3. Writes the enhanced file to the destination folder
4. Optionally archives or deletes the source file
