Change Details

This patch tries to fix the problem for Windows only. The Windows Thumbnails files are cached in an internal file called `Thumbs.db`. Blender on the other hand saves thumb images to: `C:\Users\%user%\.thumbnails\large` This is inefficient as it forces the reading of the file and causes a huge slowness at times. In addition to taking up HD space. --- This patch uses the Win 32 API to obtain an address that points to a bitmap generated for the file. Ref T87621 Thus, it is no longer necessary to read the file. --- **Unresolved problems:** - `SHCreateItemFromIDList` is deprecated - `SHCreateItemFromIDList` and `IThumbnailCache::GetThumbnail` do not work well in multithreaded (frequent crashes) --- I've spent a lot of time on this patch and I can't waste too much time on it anymore. I would be happy if someone took the lead and solved the outstanding problems.
