Cannot open XLSX files from external drive
Hi,
I have a macbook running El Capitan that has Office 365 installed, with the latest version of excel. Recently i have been unable to open excel (.xlsx) files from my external hard drive as it gives me a message stating it is corrupt and offering an option to repair - which also fails. I can however;
- Open the same file on a windows 10 PC
- Open the file in Numbers
- Open any other file on the hard drive (Word docs, PDFS, images etc) natively with no issues
- Crucially, i can copy the file to the desktop and it opens in Excel with no problems.
I am at a loss of what this could be.
thanks
(apologies if this is in the wrong section)
MacBook, OS X El Capitan (10.11.3)
