Error in ReadAffy function

I want to do a microarray analysis so I got a tar file from the GEO. When I want to read it by ReadAffy() function I get the error below:

library(affy)
dataset<-ReadAffy(compress=T, celfile.path = "GSE129166_RAW .tar")

Error in AllButCelsForReadAffy(…, filenames = filenames, widget = widget, :
No cel filennames specified and no cel files in specified directory:GSE129166_RAW .tar

This error exists even when I remove the argument “compress=T”.
How can I figure out this error?
