filesystem - remove .dat files from /home/user/ - Ask Ubuntu

i'm new ubuntu after jumping os x ship since captain tim starting lose it. i've been trying on dualboot, , love it.

but see files in home folder -think- can delete, know implode everything. can tell me if these files safe delete?

• dht.dat
• dht_feed.dat
• examples
• release.key
• resume.dat
• rss.dat
• settings.dat

edit: well, moved files trash , since experienced several freezes, crashes etc. fixed (forced) reboot, kept happening, moved items trash , far good; no more freezes (yet).

so appearantly there these files. how debug errors?

can tell me if these files safe delete?

• that decide.
• they don't belong in /home/$user/ though.
• it looks open install file in /home/$user/.
• should safe remove in opinion never know ;)

even ... command line can delete ...

rm dht.dat dht_feed.dat release.key resume.dat rss.dat settings.dat 

and if want make backup first ...

mkdir ~/backup mv dht.dat dht_feed.dat release.key resume.dat rss.dat settings.dat ~/backup/ 

i left "examples" out of though harmless delete; default directory , not part of other files listed.
