Re-use GW2.exe/datas on new PC?
Gw2.dat contains all the game’s data. Combine it with Gw2.exe and that’s all you need. GW2 doesn’t need to be installed in the traditional sense, so you can simply copy the entire GW2 folder.
The 4 GB file size limit is due to a FAT32 format. If it’s an option, reformat to NTFS, though doing so will wipe the drive. You can format a drive by right clicking it under Computer and selecting format (or Control Panel > Administrative Tools > Computer Management).
If you are limited in how much you can transfer at a time however, split Gw2.dat into multiple parts. Most compression software can do this. If you don’t have any, download 7-zip. Compress Gw2.dat and split the volume by the desired size.
I just did what you suggested… use 7 zip, moved gw2 dat into 8 pieces into my ex-HD. I also copy and paste gw2.exe (the 64 bit one), just this two? I see other files and folders such as crash file or bins… those are not needed?
You can copy the bin folders if you want, everything else other than Gw2.exe/dat is only temporary. If you don’t, they’ll simply be recreated on the first run.
You don’t have to reformat a FAT32 drive to NTFS; you can use the ‘convert’ command without losing any data. I’ve done it lots of times without issue.
