I'd like to have a portable Desktop Search program to index the 2000+ files on my flash drive. I read through the posts here (like https://portableapps.com/node/8502) but haven't found much that will work.
However, Puggle (http://puggle.sourceforge.net/index.html) is an open source desktop search engine that runs pretty fast and is visually attractive. From what I can tell (and I'm no expert) it's written in java, creates a directory .puggle under your username folder, and creates registry entries at HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.puggle\OpenWithList and
as well as a few MRU entries. You have to have the JRE installed, but I have that on my computers anyway.
Is this doable?
