Temporary file failure on fixed disk with 160GB free

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a zip file with 12 files (say 32 KB each)
2. Extract all files and modify one.
3. Use the 'Add' method to update just the one file.

What is the expected output? What do you see instead?
Fails with 'Temporary file failure' even though huge amount of disk space left. 
Same error occurs whether KAV virus scanning is disabled or enabled.

What version of the product are you using? On what operating system?
v1.90. Problem experienced under Win 7 x64 (32 bit process) with 160GB free on 
temp drive. Not experienced under Windows XP (x32) with 4.1Gb free on temp 
drive.

Please provide any additional information below.

I expect that the problem relates to the free space on the drive being so large 
that the temporary file allocation code gets upset.

Sample code fragment:
  with zip do
  begin
    Verbose := False;
    Trace := false;
    Unattended := true;

    ExtrOptions := [ExtrOverWrite,ExtrDirNames,ExtrForceDirs];
    ExtrBaseDir := userFolder + 'tempzip';
    rootDir := ExtrBaseDir;

    SpanOptions := [];
    KeepFreeOnDisk1 := 0;
    KeepFreeOnAllDisks := 0;
    AddCompLevel := 9;
    AddOptions := AddOptions + [AddRecurseDirs,AddDirNames,AddMove,{AddFreshen, }AddHiddenFiles{,AddUpdate}]; {delete from disk after moved into archive}
    AddStoreSuffixes := [assGIF, assPNG, assZ, assZIP, assZOO, assARC, assLZH, assARJ, assTAZ, assTGZ, assLHA, assRAR, assACE, assCAB, assGZ, assGZIP, assJAR];
  end;


then later, when we update one file 
      zip.FSpecArgs.add( filename );

      zip.Add;
      if (zip.errMessage <> '') then
        logError( currentFilename + ':' + zip.errMessage, zip.zipfilename );

The add triggers the error.
