Quickbooks Dsn File

QuickBooks is a richly featured accounting software developed with the main purpose to accelerate the growth of the business. The software simplifies the monotonous accounting tasks and improves the accuracy of the output. It saves abundant time and keeps the company data safe and secure.

The software saves the files with different QuickBooks file extensions in your computer. And this is what we gonna discuss along with Quickbooks dsn file.

They are as follows: .QBW, .ND, .DSN, .TLG. The file extensions can be categorized as:

  • *.QBW: It is used for major working file
  • *.QBB, *.QBM: It is used for backup file types
  • *.ND, *.DSN, *TLG: It is used for database support files

QuickBooks is no different than any other software, like others it also reads the data file:

QuickBooks: Filename.qbw

This file extension .qbw is generally known as QuickBooks company data file or company file, or QuickBooks file. It is the primary data file that acts as a storehouse of all  company financial records.

QuickBooks saves all the data file and to view the location of the saved company file:

Start QuickBooks -> Open company file -> Press F2 -> Product Information page is displayed.

When the product information page opens it displays all the important information about your QuickBooks and data, comprising the (Data) File Location. In case you  want to backup your company data, you can do so by using the internal backup function in QuickBooks: Go to File -> Back Up/Create Copy.

Backup File Types (*.QBB, *.QBM)

While creating a back up of your QuickBooks data, you get two back up options:

1. *.QBB:

It creates backup of the QuickBooks QBW file and stores the crucial financial data of the company along with templates, logos, letters, and images. All the QuickBooks data should be backed up as a QBB file in a regular basis.

2. *.QBM:

It is a portable and compressed version especially for the QuickBooks QBW file’s financial data. It doesn’t include any template or logos. The QBM file is used when there is a requirement of sharing only financial data due to the smaller size of the file.

A backup or portable file is not the main working file but functions as a zipped file that you can restore should your company data file be lost or corrupted.

Database Support Files (*.DSN, *.ND, *.TLG)

The Database support files are those that do not need to access directly.

1. *.DSN:

DSN indicates Data Source Name, which is a text file that comprise all the information needed for the QuickBooks program to connect to the QuickBooks company file.

2. *.ND:

ND indicates Network Data. It is a config. file that allows access to our QB company file.
