Hello, i have a File ( NTFSFilename-Object) and i want to check if the file is on a local-harddrive or on a network-drive. Do you know a way how can i do a check like this? thanks. best regards, Peter Dziedzic -------------------------------------- Carl Zeiss Industrielle Meßtechnik GmbH/ Industrial Metrology Softwareentwicklung/Software Development P e t e r D z i e d z i c 73446 Oberkochen, Germany e-mail: [hidden email] http://www.zeiss.de/imt Carl Zeiss Industrielle Messtechnik GmbH Carl-Zeiss-Straße 22, 73447 Oberkochen Aufsichtsratsvorsitzender: Dr. Dieter Kurz Geschäftsführer: Dr. Rainer Ohnheiser, Felix Hoben, Hanspeter Mürle Sitz der Gesellschaft: 73446 Oberkochen, Deutschland Amtsgericht Ulm, HRB 501561, USt-IdNr.: DE 811 515 346 ---------------------------------------- This message is intended for a particular addressee only and may contain business or company secrets.

Peter,
the easiest way (for not mapped network drives): ('\\myserver\somedirectory\file1' asFilename volume match: '#:\') ifFalse: ["network drive"] The reliable way needs a bit more code. Example: 'Z:\file1' (with \\myserver\somedirectory connected as Z:\ ). The testing method should read like this: PCFilename>>isNetworkName | volume typeIndex | volume := self volume. (volume match: '#:\') ifFalse: [^true "network drive"]. volume := volume copyWithout: self class separator. "I believe that GetDriveType() dislikes the trailing backslash" typeIndex := Win32FileSystem new GetDriveType: volume. ^typeIndex = Win32FileSystem new DRIVE_REMOTE I have implemented Win32FileSystem as subclass of Win32SystemSupport. The methods above are straight forward: GetDriveType: driveName "Determines whether a disk drive is a removable, fixed, CD-ROM, RAM disk, or network drive. Return code/value Description - DRIVE_UNKNOWN (0): The drive type cannot be determined. - DRIVE_NO_ROOT_DIR (1): The root path is invalid; for example, there is no volume is mounted at the path. - DRIVE_REMOVABLE (2): The drive has removable media; for example, a floppy drive, thumb drive, or flash card reader. - DRIVE_FIXED (3): The drive has fixed media; for example, a hard drive or flash drive. - DRIVE_REMOTE (4): The drive is a remote (network) drive. - DRIVE_CDROM (5): The drive is a CD-ROM drive. - DRIVE_RAMDISK (6): The drive is a RAM disk.

Hello, thanks for your support. The solution from Holger works very well. I have another question: How can i make sure when i use the copyTo:-method that i have enough space on the destination-folder. i know how to get the size of my source-file. but how can i ask how many space i have left on the destination-volume. thanks again for your help.

Peter,
Maybe there's a better way, but I'd imagine you could implement a method that opens a new file stream, seeks to the size of the file you're trying to copy, and if that works then you reset the new file stream and then copy the contents of the old stream over. If the seek fails, then I'd assume the volume does not have enough room to perform the copy (assuming the file system is not sparse or compressed). At first sight, it seems you could add the seek check somewhere along the lines of privateCopyFrom:to:, before the loop starts copying the file. HTH, Andres.

I'm pretty sure Windows Goodies has a DLLCC call implementation to check free space on volumes. _______________________________________________ vwnc mailing list [hidden email] http://lists.cs.uiuc.edu/mailman/listinfo/vwnc |
Re: [vwnc] check free space left on volume e.g. C:

However, between the time you check with DLLCC and the time
you finish copying the file, some other process could use some of the volume's
space and thus the file copy might fail despite the check. Assuming
seeking first actually allocates the volume's free space for use by the
file in question, seeking before copying would be equivalent to an atomic space
lock on the volume. Barring any I/O error, I'd expect the file copy
to run to completion if the seek operation is
successful. From: [hidden email] [mailto:[hidden email]] On Behalf Of Boris Popov Sent: Friday, November 06, 2009 12:26 AM To: [hidden email]; [hidden email] Subject: Re: [vwnc] check free space left on volume e.g. C: I'm pretty sure Windows Goodies has a DLLCC call implementation

I do not know what happens with compressed file
systems. I do not know what happens for sparse file systems that
pretend to allocate real space but keep track of file blocks that are full of
zeros. I do not know what a using DLLCC to call something that
reports free space in a compressed volume would mean,
either. From: Nowak, Helge Sent: Friday, November 06, 2009 12:52 AM To: Valloud, Andres; vwnc NC Subject: AW: [vwnc] check free space left on volume e.g. C: but what if the file system is

Peter,
others gave you valuable answers and pointed out to the rich set of problems your request might arise. Since your last request (and the acceptable solution) was Window specific, I'ld like to hint on a simple solution that works. Maybe all the possible problems are not an issue in your desired scenario. Please, open the Parcel Manager, select section "OS-Windows" and load parcel "Windows Goodies [7.2]". Thereafter you can run OSSystemSupport concreteClass spacesForVolume: 'G:\' ('G:\' is the volume name that my Windows assigned after plugging in my USB stick) This returns the basic size information for the device. The result is an Array. The first and last elements are the most interesting for you.

Hello all, thanks for your answers. There are many good answers and ideas. Holger Guhl is right. For me is a simple solution enough. I just want to copy a file from a volume to another and therefore i want to have some simple checking if there is enough size on the other volume. So the solution from Holger is enough for me.
