How do I find my Sage 50 file's version and size before converting?
Open your company in Sage 50 and check the Help menu for version details, then use Windows File Explorer on your data folder for the file size.
Knowing your Sage 50 file’s version and size is the first thing we need before any conversion or downgrade, and both are straightforward to find from inside Sage 50 or Windows.
Finding the Version
With your company file open in Sage 50, go to the Help menu and select About Sage 50 (or About Peachtree on older US editions). The dialog that appears shows the exact product, edition, and release year – for example, Sage 50 Premium 2021 or Sage 50 Quantum 2018. That detail matters because conversion paths differ depending on whether you are on a recent release, an older Peachtree-era version, or a Canadian Simply Accounting edition. If your copy has been patched or updated, note the service release number too, since it can affect how cleanly the data exports.
Finding the File Size
Sage 50 stores your data as a set of files inside a company folder rather than a single file. To check the overall size, close Sage 50, then open File Explorer and navigate to your company data folder. The default location varies by installation and version, so if you are unsure, right-click your company icon or shortcut inside Sage 50, choose Properties, and look at the folder path. Once you are in that folder, select all files, right-click, and choose Properties – Windows will show the combined size on disk. That total gives us a realistic picture of how much historical data, transactions, and list entries your file contains.
Why Both Numbers Matter
Version determines which conversion tools and intermediate steps are available, and size drives the scope of the job. A large file with many years of history may take longer to map and verify, and in some cases it makes sense to discuss whether a targeted condense or period copy would streamline the move to QuickBooks. Size can also reveal whether the file carries bloated or orphaned data that should be cleaned up before conversion rather than after.
What to Send Us
Once you have the version string and the total folder size, note them along with your target – QuickBooks Desktop Pro, Premier, Enterprise, or QuickBooks Online – and whether you are also looking to downgrade from Sage 50 Quantum to Pro or Premium. With those details, our engineers can give you a free evaluation and quote that reflects your actual file rather than a guess. Upload your backup or send us the details and we will confirm the best path forward.
