Hi friends,


How to copy a file from one directory to another

[yeye_olive]

QFile::copy().

[mouni]

it is not working...
QFile::copy(qApp->applicationDirPath(),"E:\\projects_Qt_main\\ISRO_ SAC\\Data_Encode_Decode\\DataEncoder\\File_Receive r_Transmitter -\\Added");

Added is the folder to copy file.....

The syntax is

QFile::copy("/path/fileName", "/newPath/fileName");

QFile::copy("/path/fileName", "/newPath/fileName");

To copy to clipboard, switch view to plain text mode 

Check your arguments, also check the return value.

(1) You need to copy a file to a file. Your first argument is a directory, not a file.
(2) Note that copy() does not overwrite. If the target file exists, nothing will be copied and you get false in return. If you need overwriting, delete the target file first.
(3) In Qt, use forward slashes, even in windows. Therefore: "E:/projects_etc/and_so_on"
