>I have a application rinning in vfp5 in win98 enviornment. I get a "OLE error code 0x800401ea: Moniker cannot open file" from a append general command. This command worked when the application was in win95. Are there any tricks that I must use to get this command to work in win98.

Just a guess, but the OLE server used for the file extension may have changed when you switched to Win95. I'd start by looking at the file association for the file type under both Win95 and Win98 to see if perhaps the association changed, or the server changed from a local to a remote server.
