Where is "libraries" property file in Eclipse?

[aloha.kakuikanu]

I have about 50 libraries in the Java Build Path dialog. Most of them
like

classgen.jar - \my_project\ide\lib\

are invalid. The valid ones look like this

myclasses.jar - my_project/ide/lib/

When I edit them in the dialog box, the Eclipse creates a full ugly
path like this

D:\workspace\my_project\ide\lib\

I failed to find the relevant .properties file, that I can edit
manually. The .classpath doesn't seem to be the source of the library
dialog either (because of the structure of the entries in .classpath is
uniform with forward slashes everywhere).

Actually it is .classpath (when I edited the entry it put the full
filename there). Now, what causes this ugly backslash revert for some
of the entries -- since all the entries in .classpath have pathnames
with forward slashes?
