Company is not allowing drag n drop or scanned pdfs

Let me be the first to welcome you to the Community, @Mar51.

To fix this error, make sure QuickBooks already have a folder for your attachments.

1. Browse to the location where your company files stored. Default location: C:\Users\Public\Public Documents\Intuit\QuickBooks\Company Files.
2. Create a new Attach folder.
   1. Rename Attach folder by adding "_OLD" to it.
   2. Create a new folder and name it Attach.
3. Copy the contents from the old folder.
   1. In the new Attach folder, create a folder that matches the name of the company file. Open the new folder.
   2. Create new sub-folders named Inbox and TXN.
   3. Copy and paste contents over to respective new folders from their old counterparts.
4. From the QuickBooks Company menu.
5. Select Documents.
6. Choose Repair Attached Documents Links.
7. Click Repair Links.
