Here are steps and recommended solutions to guide you in creating and restoring a QuickBooks Desktop portable company (.qbm) file.
Before proceeding, take note of the following:
Loan Manager, FAM, or QuickBooks Statement Writer information is not restored with the portable file
You will not have access to your Loan Manager (LMR), Fixed Asset Manager (FAM), or QuickBooks Statement Writer (QSW) information if you restore the portable company file on a computer other than where the QuickBooks Desktop company file is saved. To work around this, you need to copy the folders and files to the current company file location.
Loan Manager: Copy the .lmr file, which is labeled as [CompanyName].lmr, to the current location of your company file then restore it.
Fixed Asset Manager: Copy all the files from the folder specified below to the current location of your company file then restore it.
Solution 1: Copy the QuickBooks company file on the desktop
Solution 2: Try to work on a sample file
If you are able to create and restore the portable copy of the sample company file, your company file is damaged. See Resolve data damage on your company file for more information.
