While look at the /home folder, I found the followings

drwx------  2 root        root         4096 mag 29  2013 .gvfs
-rw-r--r--  1 root        root           58 ott 22  2013 .install4j
drwxr-xr-x  2 root        root         4096 ott  1  2013 .rpmdb
-rw-rw-r--  1 tigerjack89 tigerjack89    58 ott 22  2013 .install4j_jre

What they are? Can I switch them to my_user:my_group? Actually, I don't know if I can safely delete this folder and the previous .install4j file.

  • .gvfs is a virtual file system for gnome. Leave this as it is; mess with it and your system probably (most likely) will fail to work as intended.
  • .install4j is a java installer builder. Can be removed but it will depend on why you installed it and if you still need it.
  • .rpmdb is the RPM package database. If you do not use the Redhat package manager then you can remove it. If you do (it is related to the alien package) leave it as it is.

  • Thanks for your time :) Actually, I've installed both JDK 8 and JDK 7, but I don't think the installer is still needed, am I right? About rpmdb, I don't think I'm using it. However, looking inside the folder, there are various __db files. There is any program which depends on it?

  • Quoting this reply from schragge As to the .rpmdb directory, see discussion on this bug: . It gets created as a side-effect when calling old versions of dkms (before trusty, I believe) while installing any dkms-based kernel modules like NVIDIA/AMD proprietary video drivers or VirtualBox. It can be safely removed.
