How to improve performance when using FileSystemObject in ASP _ Application techniques

A test of what might be the properties caused by a performance problem, in the removal of type is the types of attributes display, the performance has been greatly improved, and then the test also proved that the Type property is used to cause performance problems.

After a moment's careful thought, the reason for the low performance of type should be that the reference to the type attribute is given to the specific type of file, which is what we see in the resource browser, such as the type of TXT file is displayed as "text document", but this type of information is stored in the system. Associated with a file name extension. When using the type attribute in the FSO, for each file object, the FSO needs to retrieve the name of the type corresponding to the extension in the system according to the extension, thus greatly reducing the performance.

Therefore, when using FileSystemObject, if you can not use the type attribute of the file or folder object, try not to use it.
