.BLK files contain blocks. .FAB files contain fabrics. These files cannot be opened. They must saved in the appropriate folder to be visible in EQ8. Then the blocks and fabrics can be viewed in the Block or Fabric Library.

Downloading a .BLK or .FAB file into EQ8 (PC or Mac)

  1. On the webpage offering the download, click to download the .BLK or .FAB file.

  3. Find the downloaded .BLK or .FAB file. Use CTRL+X (Command+X) to simultaneously copy and remove the file. The file will disappear (or become a transparent color), but it is copied.
  4. Navigate to Documents > My EQ8 > Add-on Libraries.
  5. Create a folder inside Add-on Libraries and name it something relative to your library. Moda Fabrics, for example.
  6. Open the newly created folder.
  7. Use CTRL+V (Command+V) to paste the copied file into the Add-on Libraries folder.
  8. To see the items in EQ8, click Libraries on the top menu bar. Click Block Library (for .BLK files) or Fabric Library (for .FAB files).
