Hmm, I don't think it gives what I want.
For example, I assign a file name to f,
f<- "a?b.txt"
file.path("e:",f)
[1] "e:/a?b.txt"
The resultant character is not accepted as a file name by Windows OS.
Not on Linux if you write to a smb file system, and that system won't
tell you in advance. hence you have to know it yourself or correctly
interpret the corresponding error messages.

Dear all, is there any function to assert whether a file path is
legitimate, and to convert any potential file path to a legitimate
file path?
I automate a batch of files and write them to plain text files with
cat(). The file argument of cat() is generated automatically which may
contain characters such as ?< >, unacceptable in Windows OS. What I
do at this moment is to strip such characters off with gsub(). Is
there any direct way to make legitimate file path without detailed
knowledge about the naming rule specific to a OS?
Best
