I want to rename all files in a folder, sorted in ascending creation date order by prefixing sequence numbers.
I see the syntax (.).(.) which suffixes sequence numbers. How can I reverse the placement of the sequence number from suffix to prefix, or better yet where can I find the syntax descriptions for renaming files?
(.).(.) is a regular expression which matches filename and extension. It doesn't really have anything to do with sequence numbers.
Before opening the rename window, sort the files by date. Then select them all and click rename.
Leave the dialog in Standard Rename mode. Set the old name to * and the new name to [#]_* (or whatever you want, where [#] is where the number will go).
Turn on the sequential numbering option, and set it as desired. e.g. Use 001 as the starting number if you want the numbers to be padded to three digits.
