问题
Sorry I'm a noob in excel and need help with this. Say I have the following text in my excel.
- D:/folder A/ folder B.1/text_01.txt
- D:/folder A/Folder C/ folder C.1/text_02.msg
I like to remove all the text from the right after the first occurrence "/" counting from the right.
So I would get the followings.
- D:/folder A/ folder B.1
- D:/folder A/Folder C/ folder C.1

Use LEFT() with FIND and SUBSTITUTE to find the last /
=LEFT(A1,FIND("}}}",SUBSTITUTE(A1,"/","}}}",LEN(A1)-LEN(SUBSTITUTE(A1,"/","")))-1)

If you don't mind a bit of vba, then InStrRev was almost tailor made for cases like these:
Public Function Remove_After(ByVal what As String, ByVal where As Range) As String
Remove_After = Left(where, InStrRev(where, what) - 1)
End Function

If you have Excel 2016+ with the TEXTJOIN function, you can use this array formula:
=TEXTJOIN("/",TRUE,FILTERXML("<t><s>" & SUBSTITUTE(A1,"/","</s><s>")& "</s></t>","//s[position()<last()]"))
Since this is an array formula, you need to "confirm" it by holding down ctrl + shift while hitting enter. If you do this correctly, Excel will place braces {...} around the formula as observed in the formula bar
