hello all,
Wow, this opens a big can of worms in my mind.
For instance, I'm currently working on a PD patch that writes numerous sound files to the hard drive (each file name is created via a counter: i.e. 1.wav, 2.wav, 3.wav etc.)
When I close and reopen the patch, I'd sure like to be able to look on the hard drive for the most recent file, then begin where I left off. Example, if "159.wav" was the last file written to the drive, then this new session would start at "160.wav".
As it is now, I've considered logging the filenames in a text file via [textfile] or [qlist], then open the log each time PD opens. If I could bypass this step, then my life would be a "little" simpler.
Hello all,
See, I've been thinking for some time that it would be VERY handy if PD had an object available that would allow PD to respond with information about the file system. MAX has some objects for this purpose, like;
[absolutepath] [filedate] [filein] [filepath] [relativepath]
I'm not certain that those objects would suffice, but I think they're definately a move in the right direction.
I'm very comfortable with the VBScript objects for manipulating files and I've cppied the various methods of the "FileSystemObject" below. (cut-n-pasted from www.devguru.com below). The basic gyst of it is this simple. There is a file system object which will return collections (as arrays) of drives, folders, files. Each collection has certain properties, such as "count" and "size" and "name"...then each element in the collections has more properties: such as "date", "size", "type", "name", etc.
Drives Property Returns a Drives collection consisting of all the Drive objects on a computer.
Syntax: [drvcollection = ] object.Drives

Syntax: object.GetTempName
MoveFile Method Moves one or more files from one location to another.
Syntax: object.MoveFile source, destination
MoveFolder Method Moves one or more folders from one location to another.

Is there any way for an abstraction to know the path of itsparent? Like if the abstraction wanted to save a file in its parent's
path?
