Deleting cache files and folder

Hello Everyone,

I’m new to drupal.

My drupal site frequently unavailable. And it would come back up without anything action were taken.

I suspected something is going on with caching or something … that related to performance.

Anyway, my drupal directory  is D:htdocsdrupal and I saw the folder D:htdocsdrupalcachenormal contain a lot of folders and files inside the sub-folder.

Files and sub-folders are still there even though I ran clear all caches unders Home » Administration » Configuration » Development successfully.

So, it is safe to delete files and sub-folders under D:htdocsdrupalcachenormal ?

Please help and greatly appreciate.

Thanks,

Marin
