Replacing - symbol in certain situations

Hi guys, after searching in these forums and there were no related problems like mine, so i've decided to create a new post.

So i have 1 folder with various filename pattern like this :

01010-81280.xlsx
02782-10210-01_dlb.slsx
7861-93-1930-h01_s20_tmfr-p1.xlsx
mp561-61-83211-terrain.xlsx
d07088-014a7k28h02-terrain.xlsx
tp_01011-81420_d.xlsx

i need to clear (-) symbol only at the front with - symbol, so the filename after change will be like this:

0101081280.xlsx
0278210210-01_dlb.slsx
7861931930h01_s20_tmfr-p1.xlsx
mp5616183211-terrain.xlsx
d07088014a7k28h02-terrain.xlsx
tp_0101181420_d.xlsx

the - symbol at the end of filename cannot be deleted and stay as the original filename

i tried several ways with Replace method but all of - symbol got deleted

any suggestion will be much appreciated, thanks

Your description of the problem does not make sense - it is muddled and does not correspond to all the examples given. You should define the rules that will apply to all possible desired replacements.

However, based only on the examples you have provided, you can achieve the desired results with three Replace methods...

(1) Replace: \d\K-
with: nothing
Occurrence: 1st
Use regular expressions
Removes the first hyphen following a digit.

(2) Replace: -([^-]*-)
with: \1
Use regular expressions
If there are more than one hyphens remaining in the filename the first one is removed.

3) Repeat method (2)

Reply to #2:

Sorry for not clearing up the question and making confuse.
