Hi there,
         I have a question regarding the temporary files types created when running a Delphi 3 App that incorporates
Datamodules. Why are these files created (sometimes on the desktop) and how can I prevent them from being created in the programs directory. Any ideas would be appreciated.

Regards WESTY :)

These are temporary files. I guess to you make a query with a TQuery component therefore, the bde makes a temporary database in the current directory. You cannot
prevent this the only way to prevent this is : do not use a TQuery component use TTable components and link them (if you have a query with more than one database) with keyfields.

If you need further help with this please feel free to ask me okay.

regards,

cono

cono,
        Alas I guessed they were derived from a TQuery already since (_QSQL) but I may be guessing here I have Dll's in this project as well and to use them I have to create them in the Dll source. Is this the source of the _QSQL files ie on the creation of the Datamodule object. I ask this as this is the source of all my queries and tables. Also in the forms I have been accessing there are only links to TTable components and no links to TQuery. This is why I have found it so bizarre. I give you an example. I have checked before executing the program for any _QSQL files and there are none. I can then run the program and without actually accessing a Query component these temporary files are created. The difference has been that I am unable to delete these at the runtime of the program. As soon as I exit the program they disappear. It is very strange as when I actually use a Query component a permanent file is recorded in the program directory and I then must manually delete. Very very strange I reckon.

Try TSession.PrivateDir.
See Delphi Help on this !

Ok the TSession.PrivateDir is a solution but the temporary files still remain. This is not really solving your problem or not ?

Oli2,
       Thanks for the answer works well. Cono this sis solve the problem as the files were preventing dbf's from being backed up. So by pointing the TSession.Privatedir I was able to eliminate the problem. Hope this clears it up. Thanks for your help too though.
