A couple of macro requests

[Flynsarmy]

I'm not sure if there are undocumented macros that already do this, but could you please add
{.exists.} - accepts path/path+filename. returns true if folder/file exists respectively.
{.isfile.} - accepts path/path+filename. returns true if path is a file instead of folder (some files dont have file extensions).
The reason for {.isfile.} is because if you have a file with no file extension it could look like a folder. also {.isfile.} could be combined with {.exists.} to determine if a file exists or a folder exists.

I was using filesize before but this returns 0 for empty files or folders (which would indicate that they dont exist) and md5 is ALOT slower - speed is important.

The reason i ask for these is because I currently use this code:
{.copy|{.postvar|src.}|{.postvar|destination.}.}
{.if|{.filesize|{.postvar|destination.}.}|1|0.}

It performs a copy then returns 1 if the destination file exists on the hard drive (successful copy) or 0 if the destination file doesn't exist (failed copy). This is perfect unless the file size is 0 in which case i have no way of telling if the destination file exists or not...

Another, much preferred solution would be to have both the move and copy macros return true on a successful operation and false on a failed operation. This would allow me to do this:
{.if|{.copy|{.postvar|src.}|{.postvar|destination.}.}|1|0.}

you will get both macros in next build.

anyway, i guess this is not documented, but several commands that apparently return no result, but you would like to, actually DO.
they return a white space or not.
this way, you can
{.if|{.length|{.copy|SOURCE|DESTINATION.}.}|all right|something's wrong.}

i will document this fact

{.copy|from|to.} 

missing something? not ?
{.copy|url|from|to.}
