TreeExclude specifies which drives and directories to ignore when updating the JPSTREE.IDX file. The syntax is:

 

      TreeExclude=dir1[;dir2[;dir3[;...]]]

 

Any specified drive/directory and all of its subdirectories will be excluded from JPSTREE.IDX update. For example, to exclude everything in c:\windows, d:\temp\temp2, and everything on drive g:

 

TreeExclude=c:\windows;d:\temp\temp2;g:\

 

Setting TreeExclude to the base directory of the target of a directory tree copy can speed up the copying considerably.
