Compression of Model and Drawing Files on Save

Starting with version 2026 (32.0), compressing model and drawing files on save is enabled by default. Compression saves disk space and speeds up the opening and transfer of files. Compression does not change the file extensions of files. The compression ratio and the file size limit for compressed files are set in the system settings. The default settings are optimized and recommended.

  1. Select File > System preferences > Edit.
  2. Select System settings / Save.
  3. Select the compression ratio and the file size limit for compressed files.
    • You can adjust the compression ratio using the slider. The higher the compression ratio, the less disk space is required and the faster the file transfer, but the longer the compression time. By moving the slider, the compression ratio can be set to 0, 1 or 2.
      • 0 - No compression
      • 1 - Default value.
      • 2 - Highest compression.
    • File size limit, smaller files will not be compressed. The default value varies by application. If the file is smaller than the limit, compression will not be useful.
  4. Confirm by clicking OK.
  5. Restart Vertex.
