Windows Vista has a problem with file operations, including copying, moving, transferring, or deleting files (clips). Vista does take a lot of time and runs very slowly. The phenomenon is: the "calculation remaining time" dialog box is displayed before the operation, which is quite long, which slows down the operation process and even causes the system to stall, suspend and stop responding. This failure has nothing to do with the method used - whether it's copy-paste, cut-paste, drag-and-drop or send-to - not only on two folders on the same local hard drive, on different partitions of the same hard drive or on IDE PATA or SATA And also exist on external USB portable devices, USB flash devices, mirrored drives, mapped drives, shared folders, and remote computers connected via a network or WiFi. The following is a list of 5 solutions to the problem, suitable for different levels of Vista users, you can choose, or wait for the release of Vista SP1. Searching the web, there are already many so-called solutions in this area, I don't feel very professional, or take a look at this translation: Solution 1: KB938979 Vista Performance Update This is a Vista performance update released with KB 938194, except In addition to calculating time issues, the patch also addresses many other speed issues and improves Vista performance. See here for information on these two patches: Two important Vista patches are released. Option 2: KB931770 Patch This is another official Microsoft patch that solves the problem of calculating the time (remaining time and 0 minutes remaining) when copying files from the network, which means that the copy process cannot be automatically ended. In addition, the patch may also address some other aspects of copying or moving files. Patch download: Option 3: Turn off the Remove Differential Compression RDC (Reverse Differential Compression) to synchronize data with remote resources through compression technology to minimize the number of data sent. Disabling and turning off the RDC feature can solve the problem of slow copying, moving, or deleting files. To disable the RDC step: 1. Start Menu -> Control Panel -> Program 2. "Programs and Features" area, select "Open or Close Windows Features" 3. Cancel "Remote Differential Compression" Select 4. After confirming, restart the machine. Solution 4: Disable TCP/IP "Receive Window Auto-Tuning" and/or"Receive Side Scaling" Vista's TCP AutoTuning function is a TCP/IP stack function that can be adjusted and optimized. TCP receives each network connection window size to optimize download/upload speed, while RSS (Receive Side Scaling) allows the network to load from the network adapter and balance the allocation among multiple CPUs. However, these tools don't always work as expected, and many people have solved problems such as slow multi-threaded downloads and multiple Internet browsing issues by disabling TCP/IP AutoTuning. Disabling them also resolves file copy/move bugs. For related information, see the white paper: microsoft.com Disabling Vista TCP/IP AutoTuning and Receive Side Scaling steps: 1. Open a command prompt with administrator privileges 2. Enter the following command (the latter for RSS, optional): netsh interface tcp set Global autotuninglevel=disabled netsh interface tcp set global rss=disabled 3. Restart the machine scenario 5: Use alternatives If you feel that the Vista Explorer is inconvenient, you can use other tools. Robocopy is a very good command line file copy program, which is very efficient and fast. It also has a GUI version that can be used on the desktop. Other standard copy commands, such as "xcopy" and "copy", still perform file operations as quickly as possible. You can also use third-party tools such as TeraCopy to copy/move files as fast as possible. This free software also supports integrated surgical procedures, which can completely replace the resource manager's copy/move function and is also very fast.
