Objects in library QFPINT

I have the folowing objects in library QFPINT:

 QFPBSYS1 *SVRSTG
QFPBSYS2 *SVRSTG
QFPBSYS3 *SVRSTG
QFPBSYS4 *SVRSTG
QFPBWPC1 *SVRSTG
QFPBWPJ1 *SVRSTG
QFPBWPK1 *SVRSTG
QFPBWPT1 *SVRSTG
QSF4341401 *FILE SAVF
QSF4379601 *FILE SAVF
QSF4379602 *FILE SAVF
QSF4379603 *FILE SAVF
QSF4379604 *FILE SAVF
QSF4379605 *FILE SAVF 

Can I delete this objects? I don't use Windows NT integration. What are this objects? Are the SAVF objects PTFs?

QFPINT appears to be linked with either Lotus Notes or Novell Netware.

PTFs save files (QSF) may be removed if the PTF contain has been applied permanently. As far as the *SVRSTG are concerned, I would avoid removing them. In any case, I would not remove them but rather move them to another library and see if the system still works. But first, I would check the last date they were used with DSPOBJD.
