positional relationship between them. In fact, the checksum of 0xd bytes of a long file name plays an important role. This checksum is obtained by using an operation of 11 characters of the short file name. The system determines whether the long file name matches the short file name based on the corresponding algorithm. This algorithm is not easy to use. We use a C program to describe it. Assume that the file name contains 11 characters to form a str

Everyone knows that the "desktop" store path or "My Documents" in the Windows operating system are stored by default on the C disk, and in order to reduce the load on the system disk space, we will also modify my document storage path to other partitions. However, some users do not like this after the installation of the operation, want to Win7 64-bit flagship of

Body: The so-called key-value is to store one data at a time, according to the key to store the index. To achieve the quick lookup of key, I used the b-tree storage structure. B-tree is heavily used in the index of the database, so the selection of B-tree presumably will not have too much problem. Value is the values that should be key, and his length is unknown, so to implement such a storage

, all pages are in the working set. In this case, if one or more r=0 pages are found, the longest surviving page is eliminated.Worst case, in the current time tick, all the pages have been visited (r=1), randomly choose a elimination, of course, it is best to choose a clean page elimination.9. Working Set Clock page replacementWhen a page break occurs, it is time-consuming to scan the entire table of pages to determine which pages are eliminated.An improved algorithm, which is based on the clock
