SOLIDWORKS files (*.sldprt, *.sldasm, *.slddrw) are not backward compatible. A file created in SOLIDWORKS 2024 cannot be opened directly in SOLIDWORKS 2023 or older versions. Attempting to do so results in an error message stating: "Future version file detected."
To convert these files, users typically rely on two official free tools provided by Dassault Systèmes: SolidWorks Viewer (now integrated into the online 3DEXPERIENCE platform) and the Unsuppress Feature.
A 5 MB native part often becomes a 25 MB "dumb solid" after conversion. Why? Because the converter preserves the original mesh tessellation and the new B-rep, effectively doubling the file weight. solidworks future version file converter link
This report details the available methods for opening and converting SOLIDWORKS files created in "future" versions (e.g., opening a 2024 file in SOLIDWORKS 2022). Due to the proprietary nature of SOLIDWORKS file structure, backward compatibility is not natively supported within the software. This report outlines the official workarounds, including the "Future Version Converter" tool and the "Unsuppress" method, providing direct access links and instructions.
According to leaked Q&A from SolidWorks World 2025, the current standalone converter link is being deprecated. In its place, Dassault is developing AI-Assisted Version Reconciliation. SOLIDWORKS files (*
This upcoming feature (codename: "Chronos") will attempt to not just dumb down geometry but reconstruct lost features using generative AI. For example, if a 2025 "Hole Wizard" hole is opened in 2024, Chronos will rebuild it as a cut-extrude with a sketch, not a dumb hole.
Expected release: SolidWorks 2027 (early access via Beta). Note: Direct links expire with each service pack

Warning: Be cautious of third-party sites promising a free "SolidWorks Future Version File Converter Link." These are often malware. The legitimate tool requires an active serial number.
For managers and reviewers (not designers), the eDrawings Professional viewer can open any future-version file, measure it, and even export to STL or STEP.
