1. App "PhotoshopElements_15_LS30_win64", Adobe Extractor, 1.79 GB.
2. Folder of 6 files, including the Set-Up app, 1.89 GB.
Total 3.68 GB, with no explanation of whether I need to keep them, and if so, where, or whether they are redundant and I can delete them.
Your advice would be much appreciated.
You can safely delete those files.
They are just needed during the install process.
Many thanks, very helpful.
