Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
162 words
A processing method for composing a file name from an alias to a real name in a file system, comprising a tree structure including at least one directory (10-0, 10-1) which manages subordinate directories and files (10-3) each of which is managed by one of the directories, and wherein each file is named by a designated name comprising an alias and a real name, the designated name being constituted of a sequentially arranged set of names of the related directories and the file, and each directory (10-0, 10-1) stores a name (F) of the subordinate directory or the subordinate file and a corresponding internal name (N) thereto in a pair; characterized in that the method comprises steps of: storing the internal name and a real name corresponding thereto in a pair, examining the real names corresponding to the alias (F) of the directories (10-0, 10-1) and the file (10-3) which constitutes the designated name, and composing the real name of the file.
Claim 2
Dependent Claim
42 words
A processing method as set forth in claim 1, wherein when the real name of the file has been changed, the real name stored with the internal name in a pair before the name change is changed in response to that change.
Claim 3
Independent Claim
158 words
A system for composing a file name from an alias to a real name, comprising a tree structure including at least one directory (10-0, 10-1) which manages subordinate directories and files (10-3) each of which is managed by one of the directories, and wherein each file is named by a designated name comprising an alias and a real name, the designated name being constituted of a sequentially arranged set of names of the related directories and the file, and each directory (10-0, 10-1) stores a name (F) of the subordinate directory or the subordinate file and a corresponding internal name (N) thereto in a pair; characterized in that the system comprises a space-management table (20) for storing the internal name (N) which designates a storing position therein; a stored position (S) in a storing medium of the directories (10-0, 10-1) or the file (10-3) corresponding to the internal name (N); and a real name (R) as a set.
Claim 4
Dependent Claim
255 words
A system as set forth in claim 3, further comprising: a naming server (30), a file name composing portion (50), a space-management server (40); the naming server (30) sending access request information to the file space-management server (40) when the file access is requested; when the file space-management server (40) informs the storing position (S), with reference to the directory stored in the storing position (S), the naming server (30) examining the internal name (N) corresponding to a name (F) located subsequent to the name of the directory in the designated name; the naming server (30) informing the file space-management server (40) of the internal name (N); when the file access is requested, the file space-management server (40) examining the storing position (So) and the real name (Ro) of the predetermined directory (10-0) with reference to the space-management table (20); the file space-management server (40) informing the naming server (30) of the storing position (So) and informing the file name composing portion (50) of the real name (Ro); when the internal name (N) is supplied, the file space-management server (40) examining the storing position (S) and the real name (R) corresponding to the internal name (N) with reference to the space-management table (20); the space-management server (40) informing the naming server (30) of the storing position (S) and informing the file name composing portion (50) of the real name (R); and the file name composing portion (50) composing the real name (R) obtained form the space-management server (40) and the composed file name being obtained.
Claim 5
Dependent Claim
34 words
A system as set forth in claim 3 or 4, wherein when the real name has been changed, the real name stored in the space-management table (20) is changed in response to that change.
