I don't why but this kiund of renaming is totally buged :
Search foor a space
Replace it with _
Exemple of folder :
Portail_PLM_1.01.03_PRD
Will be renamed to : Portail_PLM_1.01.03_PRD.03_PRD

I just replace 1 char with anonther. Why do I get this result ?
I understand it is a folder but I don't see why it should give any difficulties...
Thanks.
