QuickBooks desktop edition does not include file attachments when it makes a company backup data file. This will cause issues if the files need to be installed on a new computer or saved as part of normal data file backups.
The attached files are stored by QuickBooks in a folder named “Attach” with multiple subfolders.
The company file and Attach folder can be found by selecting Company > Documents > Repair Attached Documents Links.
Click the Open Company File Folder button to locate the Attach folder and company file. The Repair Links button will remove invalid attached document links. 
The company file can also be found by searching for a file with name format *.QBW.
