Bulk Text Replace

This app purpose is to replace text inside raw text files, in bulk. The usage is simple: the user must define which type of files the app will analyse (as examples, txt, css, js, java, etc), the text or regular expression (using http://jregex.sourceforge.net) to search for, the text to replace and the root directory. The output will be created in the device "download" directory, with the same input tree directory structure. The files inside will be an unmodified copy of the originals if no text replace was done, or an updated version if a replacement took place. Files with a different extension than the ones to analyse will be copied to the destination as well. This app is particularly useful to update content of programming code inside their original text files. The free version replaces text of a maximum of 5 files at once. The premium version eliminates this restriction and also removes all ads from the app.
