Find Differences In 2 PSD Files: ComparePSD
Sometimes we work on a PSD file, duplicate it and work more on it when creating a new version.
And one day, we need a layer or effect that only exists in only one of these files, search for it which can become complicated (what we're looking can be invisible as well).
ComparePSD is a free Windows software that helps finding the differences between 2 PSD files in such situations to save you time.
The software enables you to select the files to be compared from Windows Explorer.
When it is started, the files are compared layer-by-layer including layers styles (effects), styles attributes, layers visibility flags and highlights the differences.
