Reduce new items in IDE

Today, we can see that there are too many new items in the IDE of vs2008, and there are very few items you can use. If you want to delete some items, find the following directory:
C: \ Program Files \ Microsoft Visual Studio 9.0 \ common7 \ ide \ itemtemplates \ CSHARP \ WEB \ 2052 (note that it is CSHARP \ Web, not web \ CSHARP) then, delete the corresponding ZIP file. As a result, the IDE is still in normal use. Then find
C: \ Program Files \ Microsoft Visual Studio 9.0 \ common7 \ ide \ itemtemplatescache \ CSHARP \ WEB \ 2052, delete the files decompressed by zip, which still appears in IDE, an error occurred while adding.
Later, I found "How to: Find and organize project templates and item templates" in msdn"
Then you need to run a command: devenv/setup. Devenv is under the c: \ Program Files \ Microsoft Visual Studio 9.0 \ common7 \ ide directory.

After repeated experiments, we found that we changed the original CSHARP directory to csharp_d, and then created a new directory CSHARP with 2052 sub-directories, and then put several frequently-used ZIP files. This is the best practice, the content in the original csharp_d directory will also exist in the new item in C # and will not be displayed in the original box.
