I am looking for a computing expert and someone with perfect English skills to write 150-200 words on 25 different subjects/categories. Each subject is about the types of computer files (hence the requirement for a computing expert) so for example, 150-200 words on "3D Files" would be similar to the text at the top of this page: [login to view URL] or [login to view URL] The 25 categories are: 3D Audio Backup CAD Compressed Data Database Developer Disk Image Document Encoded Executable Font Game GIS/GPS Image Miscellaneous Page Design Plugin Settings Spreadsheet System Text Video Web All writing must be 100% unique (will be checked), and explain these technical topics as simply as possible in perfect English. To prove you have read this, please include the words 'filestuff' in the first line of your response. Many thanks
