File Monitor is a cross-platform file viewer that automatically redraws files when they change on disk.
You can edit an HTML document in a simple text editor and watch it update in real-time using File Monitor.
If you are zoomed into an image and if that image changes on disk, it will be automatically updated with changes while staying zoomed into and the same part of the image.
If you are keeping track of 10 different log files, File Monitor will automatically switch to the most recently modified file and take you to those changes.
Currently supported file types are text, xml, html, svg, and raster image file formats (jpg, gif, png, bmp, etc).
