    Just wanted to rename my files and now unable to get access.

    When you renamed the files you likely removed the file extension (the three or four characters after the period in the file name; .docx, .jpg, .xlsx, etc.). That extension is what systems (your operating system, Dropbox, etc.) use to determine what application should be used to open or preview a file. Without the extensions, those systems have no idea what kind if file it is.

    Put the extensions back on the files and you should be able to view/open them.

    Changing the name should not have messed them up.

    Not true. It will mess them up if you change or remove the file extension.

      UPDATE: On the desktop we discovered alias folders have been used to locate certain folders, now alias folders seem to be the problem.

        Hey Theron W., 
         
        Here’s an explanation of what our various syncing icons look like, and what they mean. If you’re seeing a small blue icon with a couple of arrows :arrows_counterclockwise:, it means that the folder/file is syncing. It may not show up on other devices until fully synced, which you’ll know when the icon shows a green circle with a checkmark in it :white_check_mark:.
         
        As far as the Update on your last post… can you please clarify?! 
         
        Thanks :wink:
