It is not possible to supervize more than approximatively 512 folders on a shared network drive using UNC path ex: \PC1234\folder, when, on using local path ex: e:\folder there is no limitation.
When limitation occured, the Win32 function ReadDirectoryChangesW (winbase.h) returns the folowing errors : ERROR_MORE_DATA 234 (0xEA) and ERROR_NO_SYSTEM_RESOURCES 1450 (0x5AA).

The UNC path lenght is 86 bytes in average, and all paths of the different folders are equal.

Is there any windows parameter to set in windows registry or somewherelse to increase or to remove this limitation ?
Thanks for help
