This may be a simple issue of permissions/ownership. Open the properties of the folder(s) in question, click the Security tab, click the Advanced button, and click the Owner tab. Click the Edit button, select your account from the list, check the "Replace owner on subcontainers and objects" box, and click OK 3 times (to close the properties dialog boxes). Once this is done, you should be able to go back into the properties dialog of the folder(s), click the Security tab, click the Advanced button, click the Change Permissions button, click Add, select your account (and click the OK button), check the "Replace all child objects with inheritable permissions from this object" and click OK. This will give your account ownership of the folder and it's contents, as well as give it full control security of the contents as well.
