Note: Copy Contents is in beta. Correction made to a screenshot that appeared earlier.
Copy Contents is a new program. It copies the contents of text or rtf files to the clipboard without opening them. It also copies image files (jpg, bmp, gif, tga, png, tif, pcx) to the clipboard, also without opening them. Right click on the supported formats mentioned and choose Copy Contents, the (successful) copied message appears briefly on the screen, now open a blank file (either text or image) and Ctrl+V to paste.
Copy Contents does (plain) text replacements to make better and more efficient use
