You are in the middle of editing a design or photo in Photoshop and all of a sudden your computer freezes or crashes. The unexpected crash causes you to panic as you realize that you didn't save your work. Unfortunately, Adobe Photoshop doesn't have an auto-save feature that automatically backs up your files. Therefore, your files are permanently lost. To prevent this from happening in the future, make sure that you frequently save your work or install an auto-save program to automatically back up your files.
Save your documents frequently. Click "File" and "Save" to save your file to disk.
Download and install auto-save software to perform automatic backups of your work. See Resources to download and purchase ATopSoft AutoSave software ($19.95 as of 2009).
Open one application at a time. Opening too many applications on your computer often causes unexpected freezes and crashes of software. If you notice your computer becoming sluggish, save your document, exit the program, and reboot. This will free up the memory and resources of your computer so that you don't experience an unexpected crash.
