In Windows 7 Offline Files Policies,
Computer(User) Configuration\Administrative Templates\Network\Offline Files\Configure Slow-Link mode
This policy setting controls the network latency and throughput thresholds that will cause a client computers to transition files and folders that are already available offline to the slow-link mode so that the user's access to this data is not degraded due to network slowness.
If you enable this policy setting, Offline Files uses the slow-link mode if the network throughput between the client and the server is below (slower than) the Throughput threshold parameter, or if the round-trip network latency is above (slower than) the Latency threshold parameter.
You can configure the slow-link mode by specifying threshold values for Throughput (in bits per second) and/or Latency (in milliseconds) for specific UNC paths.
In this policy Options guide, it suggests:
To enable the slow-link mode to apply to all shares on a server named "server" when network latency is greater than 50ms:
Value Name=\\server\* Value="Latency=50"
To enable the slow link mode to apply to the share named "\\server\share" when network throughput is less than 10000 bits per second:
Here, in the Value Name of UNC path, there's a "\*" referring "all the subfolders under current path".
However, the Wildcard("\*) doesnt apply to every scenario. For example,
If you have a UNC path like \\server\share\dir1\dir2\* you want to set Slow-link on, the Offline Files service will fail or crash when handling the slow-link policy parameters.
If user configured path for slowlink is bigger than \\server\share like \\server\share\dir1\dir2\*,Offline Files service tried to find match policy when transitioning the path \\server\share\dir1\dir2
(file://server/share/dir1/dir2)to offline/online, it would find the invalid policy which does not contain user configured latency/throughput. Then the Offline Files service crash due to this issue.
This is a known issue in Windows. This issue has been fixed in Windows 8.
