Cannot Open Files
If you cannot open a certain file, it could be due to the corruption of the file or you do not have the permissions (read/write/execute) for the specified file.
A corrupted file is difficult to recover although it can sometimes be recovered by a recovery tool or software. Usually, it will be easier to retrieve the file from a file backup if it exists on the computer or server.
For permission related issues, please ask your admin first and contact the IT Help Desk Team for further assistance.
