How do I restore a .bak file (app) on android?

[Karthik Kashyap]

I backed up my app data from my phone to my PC. These files are in .bak format. I want to restore these apps on my other phone which runs on Jelly Bean. Please help.

How was the .bak file created? Using what application or backup process?

Probably with the same app that created the backup. (Which is why I use App Backup & Restore - it backs apps up as .apk files, which can be installed directly [by taping the .apk file].)
