Files that contain the .jc! file extension are usually associated with the FlashGet application download manager. Users can use the FlashGet software to download a variety of files from the Internet and P2P file sharing applications.
When the FlashGet download manager is being used to download a file from the Internet, the partial download is saved with the .jc! file extension as the file download is in progress. This file extension will remain on the file until the file has finished downloading. When the download process has been completed, the .jc! extension is removed and the proper extension is assigned to the downloaded file.
