Versions and previews

Drop a file with the same name into Files and it is added as a new version. Version marks at the end of the name don't count: lantern_v3.fbx, lantern (4).fbx and lantern.fbx are the same file. Upload new version on the card's menu and Hand in on a task work the same way.

The Versions tab in the file's window keeps them all; step through them with Previous version and Next version.

Press Compare in the file's window: the version you are looking at opens beside the one before it, and the lists at the top pick other versions. Two pictures can be seen Side by side or as an Overlay; with two models, turning one turns the other. Esc closes the comparison.

• Pictures, and the picture inside Photoshop (.psd) files.
• 3D models: FBX, OBJ, GLB, glTF and STL; turn them, zoom and switch to Wireframe.
• Blender (.blend): the picture inside the file, and a 3D preview you can turn when the uploader has Blender.
• PDF: pages, zoom and search with Ctrl F.
• Spreadsheets: Excel (.xlsx, .xlsm, .xls), OpenDocument (.ods) and CSV, looking as they do in Excel.
• ZIP and RAR: the folders and files inside without downloading, up to 50 MB.

In messages, videos also play, and code and text files open as code blocks. A file without a preview says No preview; download it and open it in its own program.
