I am creating a package, but my files are failing to copy.

Below is what the first part of the manifest looks like. Note: I also have a folder in the package zip file called Files with all the files.

The error I am getting is:

"Failed to copy cache/upgrades/temp/VP9U4G/Files/custom/Extention/application/Ext/EntryPointRegistry/UploadContactsToTargetListByJCCCids.php to custom/Extention/application/Ext/EntryPointRegistry/UploadContactsToTargetListByJCCCids.php"

Below first part of manifest.php
