Deleting cache folder take long time because it have more than 200k files which is more than 3GB. There is quick view as Ashish mentioned.

I also faced this error in only one app.

Go through the step.

1. In you project open gradle-wrapper.properties file. Which is located in Gradle Script in Android structure. As shown in below image.

2. In that file check distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip. Here gradle version is 4.6.

3.So all cache for that project will be store in your C:\Users\Your PC Name or User Name\.gradle\caches\4.6. As shown in below image.

4. Close your android studio and delete the 4.6 folder. After deletion open android studio.

That's all. It took mine 6 hours to figure out and deleting cache folder. So I decide to post this answer. So people will not waste same time.
