On several Windows 7 boxes I'm having trouble with very large files. On my external hard drive I have a 2.2 GB Executable (extractor) as well as a 2.3 GB 7z file. However when ever I want to go to the folder I have to wait about 3 minutes before I can run the executable. During this time my hard drive activity light is going crazy, while I see little processor or RAM activity.
I can replicate this on multiple Windows 7 boxes ranging from Dual core Pentium E5300's with 2 GB RAM to a box with Dual Core Xeon Processors, 4 GB RAM, and RAID 0 HD's. It doesn't even make a difference when I use the internal HD instead of an external. This also happens when viewing a directory with a large amount of high resolution pictures. In all cases the HD activity light is going crazy, while explorer is either unresponsive or the program I'm running won't open.
