Bulk Rename Tool for Pc

It doesn't change file extensions. That's the only thing that I need it to do.

You can use this app to rename files in their current folder, or move them to a different folder with altered filenames I used this app to rename photo files taken by one smartphone to match the date-and-time pattern of files taken by another smartphone. On Phone #1 my files’ names looked like this: YYYY-MM-DD_HH.MM.SS but on Phone #2 they looked like this: YYYYMMDD HHMMSS To integrate (merge) these two sets of files with the result having all photos in chronological order, I used this app to rename the files from Phone #2 to match the filenames from Phone #1. I was able to insert hyphens (-) and periods (.) in the right places, and replace the space with an underscore. Two usage notes: (1) In an Insert or Overwrite operation, position 0 is *before* the first character, but in a Remove Char operation the first character itself *is* position 0. It would be better (app developer, please note) if the first character of the filename were always “1” in all operations. (2) In a Remove Char operation, if you want to remove the "n-th" character, specify “n” for the From position, and “n+1” for the To position. For example, if the filenames begin with ABC and you want to remove “C” (character position 2), you would expect to enter From=2 and To=2. However, this will not remove any characters. Instead, you must specify From=2 and To=3. A this app Help file is definitely needed.
