When attempting to open your company file or upgrade a file on the Mac, you may on occasion, get the message that the file you are attempting to open is not an AccountEdge company file. 

If this is not the issue, you can resolve this anomaly by:

• Make sure you are opening the file with the correct version of AccountEdge. If you attempt to open a file that has been upgraded to work with a newer version of AccountEdge and you attempt to open it with an older version of AccountEdge you will receive this message.
• You can rename the company file
• Make sure the company file name isn't more than 24 characters long
• Make sure path to the company file isn't excessively long (more than 128 characters)
• You can stop and restart FileConnect if working with AccountEdge Network Edition
• You can reboot the machine that is hosting the company file
• Optimize the company file

***Note: If you get this message when trying to upgrade a company file you can try to copy and paste the company file onto your desktop and upgrade it from there.
