If you save captured images from Snagit to your hard drive that’s fine, if you forgot to save them this is the article that tells you where to find them in your hard drive. Even though if you don’t save captures Snagit automatically stores them to its DataStore folder. So you can visit that folder and save unsaved captures to regularly saved directory on your Computer.
