This is problem with Win95.  You CANNOT delete/overwrite a file that is currently in use.  Most uninstall apps usually leave a small amount of data for the user to delete manually.  Then you have to give the user a message with instructions on how to delete it manually.  This is probably NOT what you wanted to hear.

However, you might want to experiment with the DOS "lock" command.  It may give you what you want.

You did not answer my question !
Your answer is to leave the file there, and the user delete it manually ! My question was "How to erase it ?"  If you think DOS "lock" may help me, Ok, then answer my question, tell me how to erase the file.

Thank for your fast answer, i'm very happy. :)

A batch file can delete itself, because DOS closes the batch file after reading each line.So you create a batch file which deletes the final few files, and then itself, and run it using winexec, and then exit quickly.You might have trouble exiting quickly enought so the batch file can delete you .exe, so you might also want to create a .com delay program for your batch file to call, and then delete as well.A sample batch file to delete itself is: t.bat@echo offecho heredel t.batecho too late, gone.The trouble is you then need a pif file to go woth the bat file to make sure DOS closes on exit, and stuff like that.When you winexec the batch file, run it in miniized mode...
