Re: Same file?
If you have write access permissions to the path(s) then you could try 1. Split off the file names at the end of path1 and path2 2. Save a dummy file to path1. - (OK, a problem if you don't have write access permission to the path) 3. See if the dummy file exists on path2.

Re: Same file?
Jeff, put the md5digest of url (binfile: path1) into tMD5file1 put the md5digest of url (binfile: path2) into tMD5file2 if tMD5file1 is tMD5file2 then return true else return false end if PS: this checks for the equality of files no matter the path, if you want just to see if the paths are equivalent then it is another business.

Re: Same file?
Ya, I really don't want to compare the data in the files, just whether the paths point to the same final location. Thanks, though. Jeff M.

Re: Same file?
tricky, if you can trust the input (meaning you assembled it and not your user) then something along the lines of shell(cd path1 ; pwd) will return a root relative path, you can use them to compare the folders. I believe pwd is unix-like only, don't know the windows equivalent. Also be aware that if path1 contains commands, they will execute and this potentially letal to HD and systems. Use with care and don't sue me!

There may be ways to compute a digest without reading the file into memory in other systems, but IIRC Rev's md5digest function only works on data, not file specs.
