I have been using a neat utility
CopyFilenames for some time, and find it very useful. It allows for easy filename replacement with the clipboard content without having to put the filename/foldername field into edit mode, (which can sometimes be detected as a double click if your too quick)
This idea is along similar lines
Highlight Filename
Right Click
"Paste Prefix Filename" (This would prefix the existing filename with the contents of the clipboard)
FILENAME -> CLIPBOARDFILENAME
"Paste Suffix Filename" (This would suffix the existing filename with the contents of the clipboard)
FILENAME -> FILENAMECLIPBOARD
secondary options that may be of less use to others
"Paste Prefix - Filename" (This would prefix the existing filename with the contents of the clipboard seperated by " -")
FILENAME -> CLIPBOARD - FILENAME
"Paste Suffix - Filename" (This would suffix the existing filename with the contents of the clipboard seperated by " -")
FILENAME -> FILENAME - CLIPBOARD
Another set of options that might be of use
"Paste Prefix Date - Filename" (This would prefix the existing filename with the current date seperated by " -")
FILENAME -> YYYYMMDD - FILENAME
"Paste Suffix Date - Filename" (This would suffix the existing filename with the current date seperated by " -")
FILENAME -> FILENAME - YYYYMMDD
All these might best live in a sub menu of "Paste Append" to avoid putting too much in the main right click menu
I can also see the possibility of a configuration file being needed to allow for changing the seperator and the Date Format for those needing a slight variation
