You could take ‘ownership’:
Right-click the folder, select Properties > Security Tab > Advanced at the bottom > Owner Tab > Edit > Highlight your username and put a tick in ‘Replace owner on sub containers…’ and Apply > OK. Click Yes when you receive the Security pop-up window then click OK to the Close/Reopen message. Make a note of the previous owner in case you want to change it back.

Now go back to the Properties > Security Tab. Click Edit > Add. Type in your User Account Name in the box under Enter the objects name to select. Click on Check Names > OK. Click on your User Account Name to highlight it. Check the box for Full Control > Apply and OK etc.
