Adjust the Maximum Size for that file type in the control panel.

•What if I don't want some file types to be thumbnailed by MysticThumbs?
You can select individual file types or extensions in the control panel and individually enable or disable them. If there was another thumbnail handler installed for that extension when MysticThumbs was installed, the original handler is restored when disabling.

•Where is the thumbnail cache? Can I delete it manually?
The thumbnail cache is comprised of a few system locked files stored in the User data area. The only supported way of deleting or cleaning it is using Disk Cleanup or the Clear Thumbnail Cache option in the MysticThumbs control panel, which invokes the disk cleanup tool. On network drives, thumbs.db files are generated in place when required when browsing network folders. They can be deleted manually.
