I have a somewhat strange issue with my MBP. Recently, about a week ago, I started having problems saving files from Word, Excel, and Powerpoint onto a flash drive. In Word I get the following message: Word cannot save or create this file. The disk my be full or write-protected. Try one or more of the following: etc. In Excel: Microsoft Excel cannot access the file. There are several possible reasons: The file name or path name does not exist. The file you're trying to open is being used by another program. The name of the workbook you're trying to save is the same as the name of another document that is read only. In Powerpoint: You don't have the permissions necessary to perform the operation. Use the finder to see if you have access privileges to the file or folder and that the file is not encrypted. If you don't have the privileges you want, contact an administrator for your computer or the owner of the file or folder. This happens no matter if it is a file from a year ago or a new blank document. I've tried with 4 different flash drives and they all say the same thing. I've tried formatting a flash drive, but nothing changed. The flash drives work on other machines. It's really strange and I have no clue what's going on. I'm by no means computer illiterate, but I've been unsuccessful in finding any remedies or information about the issue. I would greatly appreciate any assistance. Thanks!
