Description
I wrote this example for forum user cooladn. In the end it wasn't needed but someone may find it useful. It's yet another demonstration of the usefulness of the System plugin that Brainsucker wrote for NSIS. This example checks to see if a given disk has the desired amount of free space:
The Script
OutFile "FreeSpace.exe" !define sysGetDiskFreeSpaceEx 'kernel32::GetDiskFreeSpaceExA(t, *l, *l, *l) i' ; $0 - space required in kb ; $1 - path to check ; $2 - 0 = ignore quotas, 1 = obey quotas ; trashes $2 function CheckSpaceFunc IntCmp $2 0 ignorequota ; obey quota System::Call '${sysGetDiskFreeSpaceEx}(r1,.r2,,.)' goto converttokb ; ignore quota ignorequota: System::Call '${sysGetDiskFreeSpaceEx}(r1,.,,.r2)' converttokb: ; convert the large integer byte values into managable kb System::Int64Op $2 / 1024 Pop $2 ; check space System::Int64Op $2 > $0 Pop $2 functionend section - StrCpy $0 12345; kb u need StrCpy $1 'c:' ; check drive c: for space Call CheckSpaceFunc IntCmp $2 1 okay MessageBox MB_OK "Error: Not enough disk space" okay: sectionend
