I'm working on improving the Winamp launcher, really the only thing left to do is make the media library portable. The issue is that the media library uses absolute paths and is stored in a .dat file. Is there a way in NSIS to find B:, C:, E: or whatever the path may be and replace it with the drive letter of the flash drive? I know you can do a find and replace, but will this work in a .dat file? Also, since the initial drive letter of the path can be anything, how would I do the find and replace for it? Thanks.

check out the ReplaceInFile code used in the Notepad++ launcher.

The answer is yes, as long as the .dat file is plaintext (you can read it in notepad) and it's not unicode.
It's unicode, I can open it in notepad, but it looks all messed up. So am I completely screwed?
I know AutoIt supports unicode. If the NSIS plugin doesn't work use AI.

I'd rather not base any launchers around AutoIT. AutoIT has far more false positives than NSIS (it's used to develop quite a few bits of malware). And, as closed source freeware, it's the riskiest kind of software to base things on as the authors can just stop developing it anytime and you're screwed.
If you need some of the features of AutoIT for a launcher you're much better off using AutoHotKey.
Sometimes, the impossible can become possible, if you're awesome!
AFAICS AutoHotKey doesn't support unicode.

There seems to have been a slight misunderstanding further up the thread
The OP asked "can NSIS change letters in a binary file"
One of the answers given was that it could handle the files if they were plain text, but not unicode, with details of using notepad to see which they are.
However, Winamp .dat files are binary data. They are not any form of text: ascii, unicode or otherwise.
Having just inspected one, I can confirm that the file pathnames are embedded within it in plain 8-bit ascii, so if any of the processing languages can search and replace bytes in an arbitrary data stream, it should be doable.
Anyone know?
I went and asked on the Winamp forums about editing the library and I got this response.
