Kan, Thanks for the quick reply. BTW, I am still VERY new with XXCOPY, but think it is a great product! I saw the /S in the reference guide, but took the definition: "Copies directories and subdirectories, including empty ones." to mean this could only be used to copy files, not remove them. Yeah, my question regarding /RX was for the first statement. The /CLONE portion works well. Chaz (from this board) was very helpful yesterday in getting that statement worked out for me. Backing up my Palm data is sort of redundant. It is stored on my Palm device and at work, so the loss of the data on my home computer is not a show stopper. As to your questions: > 1. what is the legal character set for the Palm system? Not sure exactly what you mean legal character set. > 2. does it allow a space character in a filename? See below for a sample of the directory structure as an example of the various files. There are no spaces, just underscores.

It depends on the name used in the Palm itself. I am not sure if there is a limitation.

It appears to use an underscore for a space. Other than that, I am not sure. I do not do any development on the Palm, just use it all the time and do some QA stuff on one at work. > BTW, I do not own a Palm gadget, and you are the first person > who talked about using XXCOPY for backing up Palm files. Kind of overkill.

That is correct. I really need to start seeing if this will work for me at work. I have about 10 servers I manage for our software testing process. XXCOPY could be useful in keeping directory structures in tact from server to server. Thanks again Kan.
