When absolute path length is greater than 260 characters, PortableApps Platform can not open app
As suggested, I shall open a new thread to track this issue.
I have multiple apps/utilities that were categorized into folders, under PoratableApps.com folder I just put directory symlinks to the real directories.
Because the real directories were categorized into folders, sometimes its paths were a bit long. I managed it somehow.
However, whenever the absolute path length is greater than 260 characters, the app can not be opened from the PortableApps.com Platform.
