Already tried. i add .iso extention to the file and open with Daemon Tools. it can mount it but when i try to open it it says “Windows cant access this disk”
Answer #3
Do you still have the original files? 00X are not always HJSplit!
It could very well be a RAR archive with non-standard extensions, Try opening the .001 with WinRAR.
Answer #4
