Fetch is developed by Fetch Softworks for Apple macOS and Mac OS X. The software uses FCHC files to store cached data from its file-transfer operations.
An FCHC file is an internal Fetch cache file. It is not intended for direct use, editing, or exchange with other applications, and its contents may be recreated by Fetch when needed.
Open an FCHC file with Fetch on macOS or Mac OS X. Fetch manages these cache files internally, so they normally should not be opened or edited directly.
To access the related files, use Fetch to connect to the relevant server or open the downloaded files in their appropriate applications.
FCHC files are temporary Fetch cache files and do not have a meaningful conversion or export format. They are not intended to be converted into documents or media files.
If the cached information is needed, use Fetch to retrieve or save the original files instead.
