Replace File Path is a Blender add-on from uztusd for editing the file paths of loaded textures. It lists all loaded images, then searches those image paths for a given string and rewrites every match with a replacement you specify. You can also change individual paths directly from the list, which helps when renaming multiple texture folders or names at once, or when checking the paths of all textures in use.
Version 1.1.0 adds item selection: with the Select option checked, replacements run only on the ticked items, and without it they run on all items. A condition can restrict the operation to paths containing a specified string, and that string is left unreplaced. An update checker marks replaced items with a check on the right and lights them up, and you can adjust where the list splits image names from paths, along with a split UI panel.
It lists compatibility with Blender 3.0 through 4.1 and is released under the GPL license.
