Are there types of files or folders that I cannot share or synchronize?

You cannot synchronize or share the following with Live Mesh:

Files containing obscene or copyrighted material. Copying or sharing unauthorized materials, including materials that you did not create or you do not have the rights necessary for use, is a violation of the Windows Live terms of use. See the Microsoft Copyright Notice and FAQ.
Files whose names begin with a tilde (~)
desktop.ini
thumbs.db
Hidden files
Windows Systems folders
Your Desktop directory folder (for example, C:\users\[myusername]\Desktop on Windows Vista or C:\Documents and Settings\[myusername]\Desktop on Windows XP)
Files and folders stored on removable media (such as an external hard drive, flash drive, or USB drive)
Files and folders stored on mapped network drives

Live Mesh also blocks files that have the following file extensions:

.bak
.gfs
.laccdb
.lnk
.mbf
.mny
.mpc
.pst
.sav
.tmp
.wlx

Note

The .wlx extension represents files that have not finished synchronizing in a Live Mesh folder. Typically, the extension will go away once synchronization is complete. However, in some cases, the extension may persist if you have exceeded the storage limit on your Live Desktop.
