I find backslashes in path names cause no end of trouble in Stata.  Whenever dealing with filenames, my first action is always

local pathvar: subinstr local pathvar "\\" "/", all

The problem is backslashes can have special meanings when Stata tries to parse the line--they don't always get read as literal backslashes.  In particular, I suspect in your example the backslash is getting read as a modifier on the quotation mark.

Sorry, the change in macro longname construction should have read:
.local longname "`pathvar'`filename'"

Note the quotes around the concatenation.

....snipped....

The problem is that the final \ gets dropped from the path.

.di "`pathvar'"
F:\CELS\

Oddly, the initial macro seems to store this correctly

Changing the longname macro construction to...
.local longname `pathvar'`filename'
.di "`longname'"
F:\CELS35051403

...no effect
