The Portable Freeware Collection Forums

While some will likely complain this is at best liteware and at worst nagware, there's a LOT here if you mess with Regular Expressions. The major catch is the minor differences between different Regex formats mean that the formulas you come up with may not work 100% with other editors. Which is sort of the selling point for the paid version.

Still, I plan to dig into this for several upcoming edit tasks in the coming months.

Steps: Download and launch

Status: Portable, but insists on launching a browser to the "Batch Regex" program homepage after you close the program. The basic idea here is you've found a way to edit your text just right, now you can execute it across however many documents.

License: Liteware unless you the insistence to open a browser window every time it closes as nagware.

BinaryMark software creates folders/data in AppData. All of their portable software does. I contacted them about it, but they just told me to backup the appData folder as well. lol. I said, er...thanks, but not really ideal. Which is a shame because their software is pretty good.
