KDB: How to convert relative path to absolute path?
Is there a way to convert a relative path to an absolute path in KDB?
For example:
filePath: `$concat[localPath,"\",inProcessID,"\",filename]
Which returns:
`....codeproductsQShortLocator2Request Files1Locate_CCL_11-13-2018_074736.csv
And then now I want to convert this to absolute path.

Ultimately you should solve the problem of why your "localPath" variable is relative in the first place, but here is an ugly function to solve your problem:
q){hsym `$("\" sv neg[c]_"\" vs system"cd"),"\","\" sv (c:count where ".."~/:a)_a:"\" vs string x}[filePath]
`:C:UserscodeproductsQShortLocator2Request Files1Locate_CCL_11-13-201..
It is specific to windows

You can get the current working directory by typing...
q)homepath:`$system"pwd" // for Linux
,`/home/user
q)homepath:`$system"cd" // for Windows
,`C:\Users\user
To get the absolute path do...
q).Q.dd[hsym homepath; filepath]
`:/home/user/..
This should return the absolute path.
Does that answer your question?

Do you need the canonical path to the file? If you are on linux readlink is commonly available and may help:
system "readlink -f ", filepath
But this obviously doesn't help for Windows (which it looks like you are using?). I'm not aware of a similar tool.
