I have a text file (the size about 3 Mb).
I read that file and store it to table (TTable).
After all process done, and I close the file using command: system.close(FileVar).
After that I move file to specified folder using API function MoveFile.
The problem is sometimes, it returns error, called ERROR_ACCESS_DENIED
(get from GetLastError function).
It seems that the system still locks the file.
How to solve this problem?

Need help from any Delphi Expert

Are you using Windows NT?

I had this same problem with NT.  I solved the problem by adding a Sleep(200) after closing the file.
