FileExists is returning true even when the file is locked by another application. The documentation states that FileExists will return false if the file is locked. I keep getting error messages because I am trying to use FileOpen on a locked file.

The documentation is outdated for FileExists. Since FileExists supports wildcards it is no more returns FALsE for locked files.

To test for a locked file use the following code

OnErrorResumeNext
FileOpen .... as usual..., file_no
OnErrorStop

IfThen file_no, GO_TO_FILE_RPROCESS, GO_TO_FILE_LOCKED
....

Note that if FileOpen fails to open a file, the returned file number is zero. You can then test for zero to find if the file opene operation failed.
