maximum number of files to choose with tk_choose.files ?

Dear R-list,

I am running a script in which I calculate and create new
files from orginal ones.
As I have a large number of files to process, I automatize
this calculation with a loop.

First, I am choosing the files to work with.
This is done by using:

Files <- if(interactive()) tk_choose.files(default =
paste(getwd(),"/", sep=""), filter = Filters, multi=TRUE,
caption = "Files to process")

It works ok but if I am choosing approximately less than
350-400 files.
If I want to choose more files, it is not working.

Some additional information:
Files are 5kb big.
R version 2.12.1
memory.limit 4000

Someone have an idea if the function tk_choose.files
recognizes a maximum of files to work with?

thanks and greetings,
Cristabel.
