Does DPRODIR check for locked files?

[Boaz Bezborodko]

On my system there is one legacy part that builds a separate file for 
running reports of one file.  It can sometimes go out of sync and 
another program can be run to delete all it's data using DPRODIR -KA and 
rebuild it.  Sometimes, when this utility program is run, things get 
screwy somehow and opening the file in FP's utility menu causes a 
"SYSTEM ERROR".  If I copy in old versions of the key, data, and index 
files everything works fine. 


I'm wondering if part of the problem is that DPRODIR -KA can run on a 
file that is still being used by someone.  And if this is the case, how 
do I check if the file is in use before running it?  (Running on Windows.)

Thanks,
