From the KPackage listing for slocate
Secure replacement of findutil's locate
This locate can index all files on your system, but only files and directories which the invoking user has access to will be displayed.
Note: If your computer is not up 24/7 you should consider installing anacron since the database is only updated once a night.
More to the point -- have you learned about the CLI (command line interface) yet?
Which DE (desktop environment, e.g. KDE, Gnome, Xfce, etc.) are you using?
If you know the name of any
of the transferred files, then you should run (in the CLI):
locate <partial_name_of_file> | less -S
(The '| less -S' is to keep your [k|c]onsole from being overwhelmed by the output.)
Post back what you don't understand.
