Che cos'è un file PSJR?
A PSJR file is a project created by PBS Kids ScratchJr, a simplified version of the ScratchJr programming app designed for young children. It is a Zip-compressed archive that stores the contents of a ScratchJr project, including characters, backgrounds, sounds, and block-based scripts that control how characters move and interact. Since the PSJR format bundles everything included in the project, students and teachers can share a PSJR file across devices running PBS Kids ScratchJr, making it easy to transfer or back up projects.
Maggiori informazioni
PBS Kids ScratchJr helps children learn basic programming ideas such as sequencing, loops, and events through visual, drag-and-drop blocks rather than typed code. The app uses the PSJR format to save a project in a single compressed file (.ZIP file renamed as a .psjr file). Inside this file, the project's assets and configuration data are stored in several folders. An example of the contents of a PSJR file:
- backgrounds folder - Stores the background .PNG images in the project.
- characters folder - Stores the .SVG graphic of the project's character.
- thumbnails folder - Stores a thumbnail PNG of the background in the project.
- data.json - A .JSON file that contains information about the movements of the character.
NOTA: PSJR files are similar to .SJR files, which Scratch Jr uses to save projects.
Come aprire un file PSJR
You can open PSJR files with PBS Kids ScratchJr, an app available for iOS (iPad only), Android, and some Chromebook models. To open the file, you can import it from the app's home screen or select it after downloading it to the device. The standard ScratchJr app (the non–PBS Kids version) does not open PSJR files, so you must use PBS Kids ScratchJr to view or edit the project.
Since PSJR files are Zip-compressed, you can also view the contents of a PSJR file by unzipping the file with a decompression tool such as Corel WinZip, 7-Zip, or Apple Archive Utility (you may need to change the .psjr file extension to .zip for the utility to recognize the file). However, viewing the contents of a PSJR file with a decompression tool will not appear the same as opening the file with PBS Kids ScratchJr.
