I decided to defrag my flash drive, since I run my email program from it, the question is: What are the positive benefits of defragging flash drives? Also, I notice, (which could be related), some of my files got corrupted, making the size of certain files appear as 3 or 7 GB, after querying the size for all the folders and files on the root folder, my 4GB flash drive was actually displaying over 100 GB of data, I located the offending files, about 30, most of them had the name of "system file", some were hidden, some where not, I wonder if anyone else has encounter this, I am guessing that this could have been after using the RC2 version of Defraggler on my flash drive, I had a backup, so no problem here, but I thought I'd bring it up.
