I am not very good at expressions or so, and usually do minor folder renaming for my vacation and similar photos folders. My camera does add the month/day at the end of folder name, however the beginning goes 100_0725; 101_0728 and so (sequentially). A simple solution is to remove three first symbols of selected folders and add year (e.g. 2018) at the beginning at the same time. However, the fun begins when camera creates several folders for the same day, so I may have 105_0731; 106_0731; 107_0731. The file names in the folders are sequential and do not repeat, so I want to have one 2018_0731 folder, and not 3 or 5 or how many the camera did create, and I need only to merge folders.
If I try a simple rename, I get the message that rename cannot be performed because of duplicating names and told to mark the checkbox "Prevent Duplicates". I also tried checkbox "Overwrite/Delete Existing Files". Nothing helps. I tried searching in help and here, but did not find anything matching my needs. I can do manual cut/paste/delete, but I would prefer to automate, because sometimes camera adds up to 8 folders for one day (not sure about the reason).
Any ideas? Note: there are multiple days photos mixed with multiple folders of single day photos, so for part folders such simple rename works.
