How to Unlock a file

[poda]

Dear Friends, I want to delete a file which is used by other application. When I try to delete that file,it shows error as "Cannot delete file: It is being used by another person or Program.Close any programs that might be using the file and try again." On searching Google, some utility programs like "Unlocker" does this. But I am in need of the code just only to unlock the file and delete it. Could anyone help me out please? Thanks

What file that you want to delete ir depends to OS or other programs?

Not OS locked. The file is "*.tds" file generated by Borland C++ (bcc32.exe) compiler.

you can use "Process Explorer[^]" to find which application/process/thread uses the file (then up to you to kill it or not)

I think he's looking for a way to achieve it programmatically.

The quote is from the original message. I think the badly formatted message makes it difficult to read. :)

Yes I want to do it programatically. When we compile and link a project,the compiler will generate many files(like obj,map,ils,tds etc). One of them is .tds file. But this file is 'hold' by the IDE of Borland C++. How to release this 'lock' so that it can be deleted.

i don't know borland, but maybe if you just close the IDE, it will release the file, won't it ?

Ofcourse,it will release the file. But I will use the linker to create DLL as a separate process for which the .tds file has to be deleted when the IDE is open. I need to know to how to release or unlock a file which is holding by a application. Thank you
