Bro, zipped apps tab aata hai..jab apke phone ki storage kam ho jaati hai..so in that case most of the unused apps get zipped automatically inside zipped apps folder. You can unzipped those apps by getting inside zipped apps folder but first check your device storage and increase your device internal storage..
Apne device ki storage check kar lo...and don't panic is folder se koi harm ni hai..sometimes its quite handy that if you are not using any apps or its unused from long time, then you may zip those apps and can save your device storage..
