Windows 7: cannot copy large RAR/ISO files

cannot copy large RAR/ISO files

Well I've been browsing a lot of these threads, and I've come across topics similar to mine, but none have solved this problem. Basically, I am running Windows 7 64bit on an Intel core duo HP pc. I'm trying to copy RAR or ISO files larger than 4 gb's from a Maxtor external hard drive onto my pc's HDD. Everytime I get an error message saying that certain rar files are unrecognizable and gives me the option to either try again, skip file, or cancel. I had the same problem with Vista 64 bit. It has something to do with a 64 bit system because Vista 32 bit had no problem. I need to use a 64bit system for my 6g's of RAM to be utilized. Please help me out anyone. If you need more info let me know. Thanks.

Please update your system specs and provide the complete computer specs. There are a lot of HP computers out there.

Basically you can not copy 4GB files unless your using NTFS format.
Seems you need for format your HDD to NTFS.

Since Vista x86 didn't have any problems, I'm going to guess that there's nothing wrong with the drive...

I'm thinking that maybe the O/S is trying to execute rather than copy the file. In windows explorer, try right clicking on the file and click on copy. Then go to the destination folder and right click and click on paste. Let us know if that worked.

Okay, so I updated my system specs. Let me know if what I entered will suffice. I'm unfamiliar with what "PSU" means. If that is important info to help with my problem, let me know what that means and I'll recover that info.
Again, it's important to know that there was no problems when I was running my OS as a 32bit system. The problems occured when I switched to the 64bit OS, (both Vista Ultimate, and now Windows 7 Ultimate 64bit).
I really appreciate your guy's interest in helping out a poor sucker like me. Thanks for your time.

I tried this, and it looked promising at first but then I got the oh so familiar "can't read from the source file or disk," and gave me the file info to which RAR file could not be copied.

Hmmm... Ok. Try UnRaring the file to an empty directory, then copy the unrared files to the other drive into an empty directory and then rar them back up. I think it may have something to do with the file associations. Either that or the Rar files are corrupt. That's why I suggested unraring them. If they are corrupt, then you wouldn't be able to unrar them.

Good luck!

Have you tried using 7zip rather than WinRar, since you seem to be having problems with WinRar??
