Hello All: I've a published application (an executable file). It's on the MetaFrame XP server, say "D:\MyApp\app.exe". When this executable is initializing, it must reference an external file (an Access mdb file), say "..\data.mdb". (the filepath is hard-coded, and I cannot pass it as parameter to the executable) However, I have to keep this data.mdb file on the client pc. I know that client C: Drive is mapping to V: Dirve on server, thus I tried to change the working directory for the published application. I put the data.mdb in "C:\" on client pc. And then change the working directory on MetaFrame XP to "V:\MyApp". I suppose that, by "..\data.mdb" up one level of "V:\MyApp", it would reference to "V:\data.mdb" (actually, C:\data.mdb). Unfortunately, it does not work that way. MetaFrame cannot find that working directory (saying that it is invalid). Thanks very much, Y. Yang
