Is it possible for a deleted file (say a text file) to be recovered? I know that on Windows PC it is definately possible (using UNDELETE or some software), but can that also be done on a Palm OS? Thanks.

As far as I know, no such program exists or can exist. It is the Palm's hardware stucture that makes this impossible. The hard-disk on a PC keeps files intact on the disk after they've been deleted, it only removes the catalog entry for them. (Until the actual blocks are overwritten) Therefore all that the undelete program has to do is copy the data from the dead blocks to a new file. (Since the data itself remains.) On a Palm (where there is no disk) when you delete a file, the data is deleted from memory. Since there are no physical sectors in memory, the removal of a file in the PalmOS constitutes the actual deletion of the data in the chips themselves. In short, no.
