Described herein are technologies that provide an element of security related to file system operations. Individual nodes in a file system, such as a directory or a file, can be associated with information that describes how to handle letter case when a file name included in a file system operation request is used to locate a file in the file system. For example, a case sensitive designation associated with a directory can require a case sensitive match between a file name included in a request and a file name included in the directory, in order to perform the requested file system operation. In another example, a case preferring designation associated with a directory first checks for a case sensitive match between file names. If a case sensitive match does not exist, then a case insensitive match between the file names can be used to perform the requested file system operation.

Techniques for handling letter case in file systems

Techniques are described for performing a memory operation where direct memory access and logical address translation are implemented. A request for an I/O operation received that includes information indicative of whether a physical memory address may be changed and whether sector atomicity is desired. Based on the information, the requested I/O operation is performed using unmodified Block Translation Table (BTT) where the physical location associated with the requested I/O operation is changed and sector atomicity is provided, or modified BTT where a physical location associated with the requested I/O operation is not changed, or modified BTT where a physical location associated with the requested I/O operation is not changed and atomicity is provided.
