If all of the files for a given project are in or under the same directory, then
moving (e.g. `cd') to that directory should let you complete file names there.
IOW, `M-x cd', which sets `default-directory', which is the directory, by
default, for file-name completion.

And you can easily write a command that takes you directly to your project
directory, so you don't have to enter it each time.

If the files of a project are in multiple directories, then you can use Dired,
passing it the file list explicitly. Then mark specific files in that Dired
buffer and then act on the marked files.
