I suppose it would need a custom action, but couldn't one allocate an NTFS sparse file (assuming an NTFS file system, anyway)?

Subject: Re: [WiX-users] ReserveCost doesn't appear to reserve disk space Ahhhhh, so ReserveCost is to reserve space perhaps for CustomActions or other things Windows Installer might not be able to predict. Yeah, I was afraid of that. The only idea I had to "reserve" disk space was to use a TrueCrypt volume of 100MB (or whatever size) and then programmatically open it and close it when needed and store data. Of course, then there'd be various complications, such as finding an available drive letter at run-time to opening the volume, and so on. Thanks for the info, and if there are any other ideas, please do let me know.

Subject: Re: [WiX-users] ReserveCost doesn't appear to reserve disk space It's mostly internal to the install - by the time costing is complete for the target volume there should be at least that 100MB remaining. Because it's part of the cost you should get a "low disk error" if there's not enough space on that volume during the install. Programs and Features includes the cost because you said you'd be needing it :) My Win32 brain tells me that disk space isn't in a directory anyway, so there isn't a way to say that some space belongs to a particular directory as far as I know, and I know of no way that Windows would somehow know that your apps (that haven't even run yet) are the only ones allowed to use the space. --------------- Phil Wilson On Fri, Mar 14, 2014 at 9:20 AM, Alain Forget <afor...@cmu.edu> wrote: > Hi all, > > This may relate to Windows Installer in general (and not WiX specifically), > but when I use ReserveCost to reserve say 100MB for Directory A, I would > expect the amount of free space on the disk to be reduced by at least 100MB > after installation, to signify that the overall disk space has been reduced > (even though there is 100MB reserved for Directory A).
