Background:Here's how to get the number of rows in a file:If a file knows a few lines, it can control the data that gets a certain number of rows and then put it into the database. This way, regardless of the performance of reading large files, or the performance of writing to the database, can be greatly improved.Here's how to get the number of rows in a file' Error.log '; $fp = fopen ($temp _file, die("Op

Do the project process encountered to resolve more than 100 m TXT file, and warehousing. With the previous FileInputStream, BufferedReader obviously not, although readline this method can be read directly by row, but to read a 140M or so, 68W data files, not only time-consuming and will overflow memory, That is, you can't wait until you've read the 68W data, the memory overflows. So we have to use the relevant objects and methods below NiO. Use a byte

For our Golden Hill Guardian cleaning module new large file management function, do not know whether you have experienced it? We know that if the computer's system disk (usually C disk) is not enough space, our computer will become slow, and there will be some software because the system disk space is not enough to install and so on a series of problems. What should we do at this time? reload system, file backup, reload software is not 35 minutes ca

---- The author's program has some problems, and the program in the article has been modified correctly --- Use memory ing files in VC to process large files Abstract: This article uses memory ing files to access large-size files

In VC ++, the memory ing file is used to process large files-general Linux technology-Linux programming and kernel information. The following is a detailed description. Abstract: This article provides a convenient and practical solution for reading and storing large files, and introduces the specific implementation pro

Introduction file operations are one of the most basic functions of applications. Both Win32 APIs and MFC provide functions and classes that support file processing. Commonly Used functions include CreateFile () and WriteFile () of Win32 APIs () readFile () and CFile class provided by MFC. In general, these functions can meet the requirements of most scenarios, but for some special application fields, the massive storage needs may be dozens of GB, hundreds of GB, or even several TB, it is obviou

The read of the CSV large file has been described earlier (PHP reads the code instance of the larger CSV file by line), but there are still some problems with how to quickly and fully manipulate large files.1, how to quickly get the total number of CSV large file?Method One: Directly obtain the contents of the file, us

Can be used to empty directories or files, as follows: 1, first set up an empty directory mkdir/data/blank 2, remove the target directory with rsync rsync--delete-before-d/data/ blank//var/spool/clientmqueue/ so the target directory is quickly emptied If you have some very large files to delete, For example, nohup.out such as real-time update of the file, at

When we are doing a website with a large volume of data, sometimes we encounter a situation where the original data volume is too large. If we make a website, the server load is too high and the user access is very slow. At this time, we often need to divide it into multiple sub-websites, raw data also needs to be split for separate import. The following is an example of dividing an American data file into
