 In almost all cases, new material that you install should go into the

 In a MiKTeX installation, the location will in fact typically be
 something you specified yourself when you installed MiKTeX in the
 first place, but you may find you need to create one.  The MiKTeX

 You might not wish to use the 'local' tree:
+  * if the package, or whatever, is "personal" (for example, something commercial that has been licensed to you alone, or something you're developing yourself), it should go in your [[FAQ-privinst|"home" TEXMF tree]];
+  * if you //know// that the package you are installing is a replacement for the copy on the TEXMF tree of your (La)TeX distribution; in this case it is reasonable to replace the existing copy in the TEXMF tree.

 If the system is upgraded (or otherwise re-installed), a copy made in
 the TEXMF tree will probably be overwritten or deleted.  This
 may be what you want, but otherwise it's a powerful incentive to use a

 The reason one might place upgrades the distribution's main tree is to
 avoid confusion.  Suppose you were to place the file on the local
