Segue-se uma breve descrição dos subdirectórios da base de dados (onde apropriado, tamanhos de ficheiro predefinidos são apresentados):
Subdir Description Version(s) --------------------------------------------------------------------------- ATT This subdirectory has 16 subdirectories that contain All any attachment files that are used in the Mail system. Each of the 16 subdirectories contain encrypted attachment files. Files that have the .ATT extension are files that have been attached to a particular mail item. The reference to an attachment file is in the mail (.MAI) file itself. A single mail file can reference several attachments, but a single attachment file cannot be referenced more than once. CAL This subdirectory stores the online calendar files when 3.0 Schedule+ is installed. The files are stored according 3.2 to a hexadecimal (hexid) number that is assigned when the Schedule+ user first logs on. NOTE: The hexid number is NOT the same number as the one used by the Mail system! FOLDERS This subdirectory is used by the folders subsystem. All All folder files are stored here initially. Mail users may optionally move individual private folders to local storage. Individual private folders are stored in the FOLDERS\LOC\<hexid> subdirectory. Group and shared folders are stored in the FOLDERS\PUB subdirectory. This storage method is used by all versions of the MS-DOS client, OS/2 client, and Macintosh client. It is also used by the version 2.1 Windows client. the <serialno>.IDX file in the FOLDERS subdirectory is 4 bytes (fixed size). Individual <nnnnnnnn>.IDX files and the FOLDROOT.IDX file are (file size - 100 bytes) and should be divisible by 158. GLB The files in this directory are at the top of the All hierarchy of the database and serve a variety of purposes. These files contain the core of the postoffice configuration. The GLB directory also contains error message and other types of files that do not contain postoffice configuration information. This is also the default location for modem scripts. File Sizes ---------- ACCESS.GLB should be divisible by 586. ACCESS2.GLB should be divisible by 69. ACCESS3.GLB should be divisible by 512. The result for the three access files should be the same number. CONTROL.GLB 8 bytes fixed size FLAG.GLB 2 bytes fixed size GLOBAL.GLB 512 bytes fixed size GROUP.GLB (file size - 4 bytes) Should be divisible by 51 GRPMEM.GLB (file size - 4 bytes) Should be divisible by 128 MASTER.GLB 176 bytes fixed size MODEM.GLB 64 bytes fixed size NETPO.GLB (file size - 4 bytes) Should be divisible by 43 NETWORK.GLB Should be divisible by 122 PROCESS.GLB (file size - 512 bytes) Should be divisible by 197 REQCONF.GLB 512 bytes fixed size SERVER.GLB Should be divisible by 181 SVRCONF.GLB On directory synchronization server only 1024 bytes + (1024 bytes * total number of POs) TID.GLB 4 bytes fixed size GRP This subdirectory contains the group pointer files for All public and private distribution lists. The file size should be divisible by 8. HLP This subdirectory contains the Help files for the All individual Mail programs. Help is opened when the F1 key is pressed. INF This subdirectory contains the information files that All correspond to the postoffice-defined template files. The INF file contains template ("about") information for every user defined in a .USR file. The .USR file is the user list for external Mail for PC Networks postoffices and has the same filename prefix as the postoffice's MBG file. The .INF file also has this same filename prefix. There may also be an ADMIN.INF file if the local postoffice administrator has defined a custom template. External postoffice .INF files only exist if another postoffice administrator exports templates. The record format of the .INF file is defined by the associated .TPL file. There is always an associated .TPL file with every .INF file. INI This subdirectory is the default location for .INI files 3.2 used by the system; notably, by the Dispatch and External Mail programs. KEY This subdirectory contains the index files that are used All to determine the location of the mail header in the individual user's mailbag (.MBG) file. There will always be a corresponding .MBG file in the MBG subdirectory. The .KEY file contains information such as the number of new mail items since the user last logged in, the amount of unread mail in the user's mailbag, and a bitmap of deleted records in the corresponding .MBG file. The bitmap is used so that when mail is sent to a user, a vacant record position in the user's .MBG file can be found directly by examining the bitmap rather than having to sequentially process the .MBG file looking for deleted records. The file size should be 560 bytes (fixed size). LOG This subdirectory is the default location for the log All files created by the External Mail, Dispatch, and other gateway programs. The creation of these files is determined by the parameters that are specified when the various programs are started. MAI This subdirectory has 16 subdirectories that contain All any message files that are used in the Mail system. Each of the 16 subdirectories contains encrypted message files. MBG This subdirectory contains the individual mailbag files All that are used to store the Mail headers for an individual user. It is basically the file format of the first screen a user sees when he or she starts up the MS-DOS Mail or Monitor program. There will always be a corresponding key index (.KEY) file in the KEY subdirectory. The records contained in the mailbag (.MBG) file serve two purposes: - A non-deleted record acts as an index pointer to a mail item. Thus, a single mail file can be pointed to by many mailbag records. Each of these mailbag records must reside in separate .MBG files because two records in a single mailbag can never point to the same item of mail. - .MBG records contain summary information about the particular mail item. This information is used by the user agent programs to display a list of mail headers in the opening display of the user's mail. The mail file itself does not have to be read until the user selects it for processing (for example, by reading, deleting, and so forth). There is no delete flag in the .MBG record structure. Deleted status is maintained in the .KEY file, which has the same filename prefix as the .MBG file. There is a single .MBG file for every local user, of the format <nnnnnnnn>.MBG; there is a single .MBG file for every external postoffice or gateway that is defined; and there is an INQUEUE3.MBG file that is used to receive any mail from external sources and an INQUEUE.MBG file that is used for directory synchronization (Dir-Sync). Mail is delivered from the INQUEUE3.MBG file to individual mailbags via the Mailer process. The version 3.0 postoffice contains a special mailbag: SYSTEM.MBG. Mail addressed to network/postoffice/$system will be put here. This mailbag is currently used for Dir-Sync mail, but in future versions it may also be used for other system mail functions. The file size should be divisible by 116. MEM This subdirectory contains only the local members of All global groups defined at this postoffice. External addresses are not part of the member list. Each record represents a user mailbag number. These files are only created for administrator-defined groups (that is, postoffice groups) and are used for quick access by Mailer for resolving groups. The file size should be divisible by 4. The maximum size should 2000 bytes. MMF This subdirectory contains the Mail message files (.MMF) 3.0 used by the Windows clients in versions 3.0 and later. 3.2 These files are stored by user hexid number. NME This subdirectory contains the files for the postoffice All address list (POL), the global address list (GAL), gateway address lists, and the individual personal address lists (PALs) used by all clients in version 2.1, and in the MS-DOS, OS/2, and Macintosh clients in Mail versions 3.0 and later. The concept of these lists is to allow dissimilar address types to reside in the same address list. The file size should be divisible by 45. P1 This subdirectory is used by the External Mail program to All store temporary mail files during a communications or postoffice-to-postoffice (PO-to-PO) delivery session. TPL This subdirectory contains the template files used by the All local postoffice and gateways. USR This file is the address list of users and groups for a All particular postoffice. The postoffice that this list represents is an externally defined postoffice. If this file exists, its prefix filename will match the external postoffice's .MBG filename. This file can be created or updated using the Mail Administrator program (ADMIN.EXE) or it can be created or replaced by the External Mail program when it receives an exported user list from this postoffice. The file size should be divisible by 53. XTN This subdirectory contains the external postoffice All definition files. Each .XTN file contains all of the postoffices that are defined at an individual network. For each network that is defined in the NETWORK.GLB file, there is an associated .XTN file. This file is a series of records, where each record defines a different postoffice at this network. The purpose of this file is to provide routing, naming, and sign-on information for external services/postoffices. Postoffice records also contain connection information, statistics, and various configuration options for that postoffice. Each postoffice record contains a file pointer reference to its mailbag. When an address list of users is created for this postoffice, there will also be a .USR file and, possibly, .TPL and .INF files with the same file prefix as the .MBG file. The file size should be divisible by 698.
