changing the location of the plugins folder

[Jennifer West]

Hi,

On the Windows platform, can you configure ImageJ to look for plugins  
in multiple folders? How do you do it?

I can change the plugins folder by adding the following to ImageJ.cfg:

-Dplugins.dir=H:\plugins -cp ij.jar ij.ImageJ

and that works. But if I include another folder:

-Dplugins.dir=C:\Program Files\ImageJ\plugins;H:\plugins -cp ij.jar ij.ImageJ

Then I get an error that ImageJ can't find the main class.

I thought the space between "Program" and "Files" might be an issue so I tried

-Dplugins.dir=C:\Program/Files\ImageJ\plugins;H:\plugins -cp ij.jar ij.ImageJ

But then I see no plugins at all. I also tried quotes, but then it  
does not launch at all.

Does anyone have any suggestions?

Thanks!
Jennifer

No.  ImageJ only supports one plugin folder.

Correction to what I write below:

There is a utility called NTFS links that can create NTS soft links and
this way you could even "mount" another drive in a subdirectory of the
plugins folder! (Did not try it myself!)

Hi there,

at least under an unix-ish operating system/file system there is no real
problem to set a (soft/hard) link so that the 2nd directory would appear
and behave as a subdirectory of the regular plugins folder.

Interestingly, NTFS has a "hard link" support too, but there seems to be no
GUI or command line support. Also it seems - in contrast to unix filesystem
- that NTFS hard linking only works
within ONE filesystem, not accross any of the mounted filesystems as with
Unix.

Hi Jennifer,

I just tested the probable solution on Windows using "NTFSlink" I
suggested, it seems as long as your other drive is another harddrive with
NTFS it works great, (created another directoy
on a second drive, copied some plugins there, linke dthis directory into
the IJ plugins directory with NTFS link and restarted IJ and the new
directory appears in the plugin list and
I can start these plugins). However, it probably wil not work if your H:\
is a network drive (in my cases of a drive mounted from a Samba/Linux
server I cannot set a NTFS hardlink)!

Maybe this helps

Sincerely

Joachim
