Finding the Directory Name

If you have a need to find out the directory in which your workbook is saved, you may be tempted to use a macro to figure out the answer. While this is a valid approach (and relatively easy), some people are intimidated by macros or don't want to use them within the workbooks. The following worksheet formula will return the directory in which the workbook is stored:

=LEFT(CELL("Filename",$A$1),FIND("[",CELL("Filename",$A$1))-1)

If you use this formula in a workbook that is brand new—one that has yet to be saved—then it will return a #VALUE! error. This happens because the filename has not yet been set, and the LEFT function cannot return a portion of something that is not there. To avoid the error, simply encase the formula in an IF function, as follows:

=IF(CELL("Filename",$A$1)>"",LEFT(CELL("Filename",$A$1),
FIND("[",CELL("Filename",$A$1))-1),"")

In this variation the CELL function is used to determine if the filename has been set. If it has, then the directory name is extracted and returned. If not, then an empty string is returned.
