QB Issue Resolution:
The following table describes the file extensions that QuickBooks uses for files that it creates, imports, or exports.
| Extension | File type | Description |
|---|---|---|
| .DES | QuickBooks form template | QuickBooks provides a variety of templates that you can use for your forms. |
| .IIF | Intuit Interchange Format file | You can import and export lists and/or transactions using text files with an .IIF extension. |
| .ND | QuickBooks Network Data File | A configuration file that allows access to the QuickBooks company file. Do not delete this configuration file. |
| .QBA | Accountant’s Copy working file | When you export your QuickBooks data for your accountant to review, the accountant restores the export file on his or her computer as a file with a .QBA extension. |
| .QBA.TLG | transaction log file (for Accountant’s Copy) |
When you back up an Accountant’s Copy, QuickBooks starts a log of transactions that you’ve entered since the last time you backed up. The file is created during backup provided you have set a verification level. In case of accidental loss of data, Technical Support can use your most recent backup in conjunction with the transaction log file to recover your data. |
| .QBB | QuickBooks backup file | When you back up your company file, QuickBooks saves the backup file with a .QBB extension. To open a .QBB file, go to the Filemenu and clickRestore. |
| .QBM | QuickBooks portable company file | When you want to e-mail or move a company file, QuickBooks creates a compressed version of the company file with a .QBM extension. |
| .QBR | Report template | When you export the template for a memorized report, QuickBooks saves the file with a .QBR extension. |
| .QBW | QuickBooks for Windows company file | When you create a company file, QuickBooks saves the file with a .QBW extension. For example, if you enter MyBusiness as the company name, QuickBooks saves the file as MyBusiness.QBW. |
| .QBW.TLG | transaction log file (for QuickBooks company file) |
When you back up your company file, QuickBooks starts a log of transactions that you’ve entered since the last time you backed up. In case of accidental loss of data, Technical Support can use your most recent backup in conjunction with the transaction log file to recover your data. This log file is also used if you sync your QuickBooks data with certain online services using Intuit Sync Manager. This allows ongoing syncs to happen much more quickly than the initial full upload of QuickBooks data into your online services. |
| .QBX | Accountant’s Copy (export file) | When you export your QuickBooks data for your accountant to review, QuickBooks creates an Accountant’s Copy with a .QBX extension. |
| .QBY | Accountant’s Copy (import file) | When your accountant is finished making changes in an Accountant’s Copy, he or she provides you with a .QBY file to be imported into your company file. |
