You had actually guessed right. The list of folders and paths used by the app are in:
~/Library/Application Support/Less app/lessDataFile.lessData
It's a binary plist (Property List) file, and from the look of the structure of the file, it's not meant to be messed with. It looks like an unintuitive serialization/dump of the internal state of the app.
It seems to store its preferences in this other binary plist file:
~/Library/Preferences/com.incident57.Less.plist
...but this file doesn't contain any of the folder paths used by the app. That's all in the lessDataFile.lessData
file you'd already found.
It's standard practice for Mac OS X apps to store their preferences in a plist like that (that location, that naming scheme).
You can read and edit binary plist files with Xcode (and many other programming-oriented text editors for Mac OS X), or with the command-line tools PlistBuddy(8)
, or defaults(1)
. Or you can convert them to XML text files with plutil(1)
. Some tools for working with plists expect the file name to end in .plist
, so keep that in mind if you're struggling to get a tool to open the .LessData
file.
