<![CDATA[How to dynamically change the directory that files are read from?]]>I have hundreds of data files in different subdirectories that I read into wavetables. I want to dynamically change the directory that the files are read from. I tried sending a dir message to pdcontrol, which appeared to work, but pd does not find the files in the subdirectory. How can I dynamically change the directory that files are read from?

in the one that works it looks like you are specifying the directory as part of the path?

so instead you could have $1\0298a.seismic and put [symbol accel( etc. in to read from diff directories.

Replace "disp" in the read message with a $1 and instead of banging the message send the directory name accel vel or disp into it,,

The example I gave was a simplified version of what I'm doing. I have 129 files in each directory. The file names are the same in all the directories. (There are three directories now, but there will soon be more.) I have a selectable list of file names and I want to be able to open whatever file was selected in the currently selected directory. I'm currently using $1 in the read message to pass in the selected file name, so I can't use it for the directory name. Is there a way to put two variables in the read message?

Look at the bottom left. Also click on [pd dollar-variables]

Although you probably want each array in an abstraction with the file name as an abstraction argument or you will have problems with multiple arrays with the same name.... so ignore that....
So see the zip below which uses abstractions.
Dollars in objects are translated as the patch is opened so then you could replace [pack s s] with [pack s $1] and remove the [loadbang]
[EDIT... you cannot as the $1 needs to be a symbol so [loadbang] is still required.... I have changed that in the zip]

The directory selection could be in your master patch and a message sent to the abstractions to change directory.
Note that the $2 in the message is the same as the $1 in the objects in this case.....

Try doing something like this to organise your files and the setting of the tables...... this.zip

You will need to put all the abstractions in your Master patch but you only need to do that once. Future edits of the abstraction where necessary will be easy.
David.

see openpanel-help for modes: 0 file 1 directory 2 multiple files

The three directories contain the same named files, and the files have different text
I should point out that [file handle] is for binary files and is only used to quickly illustrate the file contents are different

Does that work? and does Pd still find objects once another directory is set if you then use [declare]?
I have used [file glob] to find directories and search files in the past, but never changed the working directory.

Your example with the close, open message works on my system, but when I tried to use the read message to read the file, I got a "can't read" message. Any ideas on how I can make this work? Thanks!

Edit: I opened issue #2888 on github for the problem that [file cwd] doesn't work with read.

This looks promising. I'll give it a try.
