about lost job after reinstall the game to another pc

[HyoMinPark]

If you have a USB drive, you can try to transfer your saved UI/gearset data from one PC to another PC—

Go to wherever your Game folder is, and go into the FINAL FANTASY XIV - A Realm Reborn folder.
Look for the folder(s) titled FFXIV_CHR004000xxxxxxxxxxxxx (there will be a series of letters/numbers).
Take the files inside the folders, copy them, and paste them onto your USB drive.
Transfer them to your new PC. Place them inside the FINAL FANTASY XIV - A Realm Reborn > FFXIV_CHR0040000xxxxxxxxxxxxxxxx folder of the character you want the settings to apply to on your new FC.
Your HUD, gearsets, etc. should appear once you close down the game and relaunch it. I’ve done this before with no issues.

Hmmm you do realize only your settings change when you reinstall right? everything is in the inventory key items for your job crystals. -.-/ maybe see the online help manual for assistance. This is what happens when people really don't read the instructions manual or put attention to tutorials as things get unlocked. -.-.

No need to be rude. OP asked a question. Why don’t you try to answer it instead of being rude to him?
