The hidden parameters of Windows Commander are publicly available.

You must have heard about the name of the Super File Manager Windows Commander (WinCMD). It has some hidden parameters that can work better by modifying these hidden parameters.

To add these hidden parameters, you must find the WinCMD. ini file (usually in C: \ windows or C: \ winnt) and add it under its [Configuration] section.

The CopyBlockSize and CopyBlockSizeOther parameters determine the size of each read/write block in WinCMD during file copy. The default value and minimum value are both 32 KB ). The difference is that the previous one indicates the size of the read/write block when the copy operation is performed on the same physical hard disk, and the last one indicates the size of the read/write block when the copy operation is performed on different physical hard disks. For example, if you want to copy a file of KB, since 33 is greater than the default value of 32, WinCMD reads and writes the file twice during copy. The first read and write operations are 32 KB, and the second read-only operation is 1 kb, it wastes a lot of time. I think you can understand that this parameter cannot be too small, but the bigger the parameter, the better it is? No! Each read/write operation on the disk will verify the correctness of the copy file. If there is a byte error, the computer will read and write again. Therefore, setting too large may not be worth the candle. We need to select an appropriate size. Interested readers can use the Performance Monitor provided by Windows to observe the disk performance to determine the size of this parameter. For details, see.

The CopyHugeBlockSize and CopyHugeBlockSizeOther parameters determine the size of the read/write block of WinCMD when copying a large file. The minimum value of the previous one is 10 MB, and the minimum value of the next one is KB. Files larger than this size are read and written directly by WinCMD without hard disk cache. When copying other small files, the CopyBlockSize setting is still used. This setting has no default value. If this setting is not found in WinCMD. ini, WinCMD does not use the direct read/write mode when copying large files. The difference is the same as the previous one. The first one is used for the same physical hard disk, and the last one is used for different physical hard disks. Because the hard disk cache is mainly a buffer file path, it is useless to search for files quickly but copy large files, because after the hard disk determines the file location, the cached content is rarely updated, therefore, disabling the disk cache can speed up copying files.

The following settings are recommended for WinCMD:

CopyBlockSize = 1024

CopyHugeBlockSize = 10240

CopyBlockSizeOther = 128

CopyHugeBlockSizeOther = 1024

When the above settings are used, WinCMD Copies files differently. For example, when copying a 20 mb file on the same physical hard disk, the progress displayed by WinCMD is not as advanced as 1.1 points, but jump to 50% at once, and then jump to 100%. In fact, the parameter CopyHugeBlockSize = 10240 is working. I don't know if it works.

ExplorerForCopy. This parameter determines whether WinCMD uses its built-in Copy function (0) or Windows Explorer (1) to Copy files. If you use Explorer to Copy files, the Copy progress bar of WinCMD will not appear during the Copy process, but the Explorer progress bar will appear. In addition, if a file with the same name needs to be replaced, the displayed dialog box is also in the Explorer style.
