You don't have to use sed for such a simple task if you're using a bourne-type unix shell:

Code:
% f='C:/folder1/abc/file.txt'; printf '%s/\n' "${f%/*}"
C:/folder1/abc/

Anyway, using sed it would be:


Code:
% f='C:/folder1/abc/file.txt'; sed 's [^/]*$  '<<<"$f"
C:/folder1/abc/

If your shell does not support here-strings (the <<< syntax), use printf ... | sed ...

There is an external (to the shell) command for that too, it's called dirname.

Code:
% f='C:/folder1/abc/file.txt'; dirname "$f"           
C:/folder1/abc

alternatively,

Code:
file="C:/folder1/abc/file.txt"
path=${file%\/*}

echo $path
C:/folder1/abc
