Unable to delete a file from Data partition!

There is a file on my xt1068 with path /data/data/com.google.chrome/app_webview/Cache/8f7f69bc88662934_0 .I am unable to delete this file through any method.It is not visible in es file explorer or any other file manager,i have tried deleting the folder but it fails even after providing root permissions.I have tried deleting it by wiping data partition via TWRP and CWM but both failed.I also tried deleting it using aroma file manager and TWRP's flile manager but no luck.Due to this file i can't create or restore nandroid backup.While installing any new ROM i need to go to the TWRP's file manager and i manually delete all the folder's except the one i mentioned above,to perform a clean install.I have also tried restoring to stock firmaware using fastboot but after installation of rom the file still remains there.
My TWRP always shows this message:"E:Unable to stat '/data/data/com.google.chrome/app_webview/Cache/8f7f69bc88662934_0'
Please help me with this.
