Purge
After a delicious, yet very heavy, dinner at Assaggio Ristorante, we came home and Hubby made a beeline for the bed and knocked the heck out, sprawled out on the bedspread in his “going out” clothes. That gave me some alone time, just me and my iMac, to get some business done. In the past few hours, I managed to back up my entire photo archive (2000-2007) to my new 500 GB external hard drive and purge my e-mail account of unnecessary messages saved in my InBox. I went from 1764 messages in my Inbox to 7. I didn’t do a mass purge, but actually ended up skimming through the subject lines of all 1764 messages and filed the ones that may come in handy someday. Let’s see how long my InBox can stay in the single-digits. My guess is less than 24-hours.
I wonder if you Mac geeks out there can give me some advice. I’m trying to make my external HD compatible with both Mac and PC. Using Disk Utility, I formatted it as “MS-DOS” (i.e., FAT32), but quickly discovered that it prevents me from transferring large files (over 4 GB). Any suggestions on a work-around?
My body has been pretty adamant about getting to bed before midnight these days, so I better get a move on. It has been a very long week. Thank God for weekends.

Unfortunately thats the limitation of trying to do the best of both worlds. FAT 32 is limited in the amount of characters in each file name as well. What I usually tell clients is to just make it Mac compatible and then just share the drive on your network via windows sharing in System Preferences > Sharing > Windows Sharing
This way you have no worries about moving the drive back and forth between computers and both can access the drive.
What kimonostereo said.
Alternatively, you can format the drive as HFS as use something like MacDrive to read it on Windows.
Personally, I stay as far away from Windows as possible.
You could use MacDisk or MacDrive, etc; but those are licensed products, and generally the license will prevent you from moving from machine to machine with any ease.
The FOSS solutions right now are pretty lacking though..
What are you after? Sharing the content, or sharing the space?
If the latter, you could do something like this
