jclay Terminology is supposed to be following:
- Indexing means program reads content of your archive for the first time and loads in into its internal database
- Scanning means program already finished indexing, and now it checks if there are any changes in your archive to reflect in database
- Importing means program moves files to your archive from some other location (other drive, phone, SD card, telegram, etc.)
I guess you have a phone always connected to your PC and every time you start an app it detects it and checks for new images. You can disable automatic import in the Import dialog that you can call from the main menu.
