QFile::size() and QFileInfo::size() both return the size of the link's target and not of the .lnk file itself.

QFile::open() does however open the .lnk file.

The attatched sample app shows the problem:

Output:

path : "C:/Users/Kim/Desktop/wat.exe.lnk"
symlink: true
target : "C:/wat.exe"
QFileInfo.size : 1018368 // this is wrong
stat.st_size : 716
QFile.readall.size: 716
QFile.size : 1018368 // this is wrong

path : "C:/wat.exe"
symlink: false
target : ""
QFileInfo.size : 1018368
stat.st_size : 1018368
QFile.readall.size: 1018368
QFile.size : 1018368
