Understand that many different Unix filesystems exist. We don't know which one you are using. But in general...

"Since all files (File1 to File20) are supposed to have been present in the same directory (DIR) is it possible to succeed in identifying access and deletion timestamp of only a subset?"

Yes it it quite possible. Deleting a file frees an inode. The inode continues to have some useful info in it... until it happens to be re-used.


"Also File1 to File14 are assumed to be created and deleted earliest than File15 to File20 (fwe month to several years for some files)"

I don't know why you assume that. Files can be deleted wheneve the owner wants. No need to delete in the sequence they were created. Even if you have some rule in place and follow it closely... perhaps the bad guy who broke in did not follow your rule.


If you want to verify your experts opinions, hire a second set of experts to examine the same system. Do not tell the second set what the first set said.

SYNOPSIS

       install-info [OPTION]... [INFO-FILE [DIR-FILE]]

DESCRIPTION

       Install or delete dir entries from INFO-FILE in the Info directory file DIR-FILE.

	      delete existing entries for INFO-FILE from DIR-FILE; don't insert any new entries.

       --dir-file=NAME
	      specify file name of Info directory file.  This is equivalent to using the DIR-FILE argument.

       --entry=TEXT
	      insert  TEXT as an Info directory entry.	TEXT should have the form of an Info menu item line plus zero or more extra lines starting
	      with whitespace.	If you specify more than one entry, they are all added.  If you don't specify any  entries,  they  are	determined
	      from information in the Info file itself.

       --help display this help and exit.

       --info-file=FILE
	      specify Info file to install in the directory.  This is equivalent to using the INFO-FILE argument.

       --info-dir=DIR
	      same as --dir-file=DIR/dir.

       --item=TEXT

       --section=SEC
	      put this file's entries in section SEC of the directory.	If you specify more than one section, all the entries are added in each of
	      the sections.  If you don't specify any sections, they are determined from information in the Info file itself.

       --version
	      display version information and exit.
