If you save captured images from Snagit to your hard drive, that’s fine, in case if you forgot to save them this is the article that tells you where to find them on your computer. 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 system.
Finding location of Unsaved captures of Snagit
Paste the below path in the Run dialog box on your Windows OS.
In Windows XP: C:\Documents and Settings\<User name>\Local Settings\Application Data\TechSmith\SnagIt\DataStore
In Windows Vista/ 7/ 8 and Windows 10: %LOCALAPPDATA%\TechSmith\SnagIt\DataStore
Update: Snagit 12 or later versions, lets you change Snagit’s automatic stored files location to the desired one you want, for more details, read: Snagit 12.2 Update adds Light Theme Option for the Editor, improves Scrolling Capture
