While constructing some tests of symbolic link code in R, I got an odd warning when trying the remove a symbolic link:
file.create(tfile <- tempfile()) #[1] TRUE file.symlink(tfile, tlink <- tempfile()) #[1] TRUE unlink(tlink) #Warning message: #In unlink(tlink) : # cannot delete reparse point 'C:\Users\wdunlap\AppData\Local\Temp\Rtmp0oB1gl\fileedc792515a3', reason 'There is a mismatch between the tag specified in the request and the tag present in the reparse point. #' file.exists(tlink) #[1] TRUE I can remove the symbolic link, without any warnings, if it is in a directory that I remove with unlink(recursive=TRUE): dir.create(tdir <- tempfile(fileext=".dir")) file.create(tfile <- file.path(tdir, "file")) #[1] TRUE file.symlink(tfile, tlink <- file.path(tdir, "symlinkToFile")) #[1] TRUE dir(tdir) #[1] "file" "symlinkToFile" print(unlink(tdir, recursive=TRUE)) #[1] 0 file.exists(tdir) #[1] FALSE file.exists(tlink) #[1] FALSE (I didn't know symlinks were even possible on Windows, but they are in Windows 7. Sys.readlink() does nothing useful on Windows.) > sessionInfo() R version 3.3.0 (2016-05-03) Platform: x86_64-w64-mingw32/x64 (64-bit) Running under: Windows 7 x64 (build 7601) Service Pack 1 locale: [1] LC_COLLATE=English_United States.1252 LC_CTYPE=English_United States.1252 [3] LC_MONETARY=English_United States.1252 LC_NUMERIC=C [5] LC_TIME=English_United States.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base loaded via a namespace (and not attached): [1] assertionTest_0.5 Bill Dunlap TIBCO Software wdunlap tibco.com [[alternative HTML version deleted]] ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
