!C is a Hobetta image file extension associated with ZX Spectrum computers, which were one of the first types of home computers, released in the 1980s by Sinclair Research Ltd. They supported an 8-bit color rendering, hence the name Spectrum, as opposed to their predecessor models, the ZX81, which could only render black-and-white images. The !C format is now considered a rare format, but can be converted to formats that are more accessible and popular.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert multiple !C files as once.
