How can I rescue a PTG painting that won’t open in ArtRage?
If you receive an error message and are unable to open a PTG file, then it probably means that your ArtRage painting was were corrupted at some point. Damaged PTG files usually result from interrupted saves (for example, if the computer shuts down or ArtRage crashes). We will do our best to help troubleshoot the source of ArtRage errors, but usually cannot fix corrupted or partial files.
However, if you can see the image thumbnail then that means that the PNG preview image is intact. If you use File > Import Image File to open the damaged files, then it will import the PNG thumbnail.
This PNG file is the full size of your painting and high quality. It won’t rescue your layers or other paint information, but it will give you something to work with.
Backup Save Files
If crashes happen frequently for any reason, or you are working on an important painting, we recommend turning on the Store Backup Files option. You can find it by going to Edit > ArtRage Preferences > Advanced > Store Backup Files.
Adjust the slider to the number of backups you would like to keep.
Important: This function does not save a duplicate file. Instead, it keeps a history of previous saved versions.
Every time you save, it will delete the oldest backup file, and save the latest changes as a separate file, so if you have made important changes, save twice to update the older back up and the file you are actually working on.
