10? Depends on the size of each file and available system memory. If the files are fairly large, then you may need to DEM the route in steps, merging only a few at a time. FWIW, the greatest number of DEMs I've had to "stitch" together was four, with each in 70~80mb range.
OK each file of DEM is 9,069 KB so that means the total of 10 DEM files is 90690 KB and convert to 93.8 MB. It look like that I exceeded over a little which should be in 70~80 MB range. I am going to figure it out first how to merge 5 files at a time then the next 5 files to merge at a time. Or do I have to merge 4 files first then 4 files then 2 files that would make of 10 files together?? Not sure about system memory you mean the computer? If it is then I have 1GB memory in the computer. Let me know about this.
Thank you again,

This "guide" is tailored to the latest changes on the USGS seamless site.
...how do you use the seamless DEM on DEMEX, I know how to use normal DEM but not the seamless, it seems to be in a different file format...
