QuickBooks 2015 default company file location

After changing a file name or location, the previously attached documents are no longer available.

Why this is happening

When you use QuickBooks Attached Documents with locally stored attachments, an Attach folder is created and stored by default in the same location as your company file.The connection between your Company File and your Attached Documents will break if you rename or move your company file.

How to fix it

Browse to the location where your company file is stored and open the Attach folder.Follow the appropriate steps below:
If there is a folder with the new company name:
Open the folder with the OLD company name.Copy the contents of the InBox folder and paste them in the InBox sub-folder of the folder with the New company name.Copy the contents of the Txn folder and paste them in the Txn sub-folder of the folder with the New company name.
If there is NOT a folder with the new company name, change the name of the folder to match the name of the new company file. Use exactly what is in front of the .qbw.
Open the Company menu and select Documents.Select Clean Up Attachment Links.
