pax is an archiving utility available for various operating systems and defined since 1995. [1] Rather than sort out the incompatible options that have crept up between tar and cpio, along with their implementations across various versions of Unix, the IEEE designed a new archive utility pax that could support various archive formats with useful options from both archivers.
A user can use a Data Link Properties dialog box to save connection information in a .udl file as an alternative to directly specifying them by hand in a connection string. Consequently, these files provide a convenient level of indirection. Additionally, the dialog box specifies a number of alternate OLE DB data providers for a variety of ...
ACFS [2] is a standard-based POSIX (Linux, UNIX) and Windows cluster file system with full cluster-wide file and memory mapped I/O cache coherency and file locking. ACFS provides direct I/O for Oracle database I/O workloads. ACFS implements indirect I/O however for general purpose files that typically perform small I/O for better response time.
Files with hard links in multiple directories have multiple reference items, one for each parent directory. Files with multiple hard links in the same directory pack all of the links' filenames into the same reference item. This was a design flaw that limited the number of same-directory hard links to however many could fit in a single tree block.
In fact, files in a virtual folder do not even need to be stored as files on the hard drive. They may be on a network share or in a custom application datastore such as e-mail inbox or even a database. Documents cannot be "stored" in a virtual folder, since physically a virtual folder is just a file storing a search query.
Permissions that affect files and subdirectories include: Read (r) allows a user to look at the contents of files in a directory and list files in subdirectories. Files that are to be granted read access to any user, including the owner, need to have the standard UNIX "owner read" permission set. Write (w) allows a user to modify files in a ...
Directory (D): The entry is a subdirectory, containing file and directory entries of its own. Reparse Point (L): The file or directory has an associated re-parse point, or is a symbolic link . Offline (O): The file data is physically moved to offline storage (Remote Storage).
