I believe you can put the wallet software anywhere you like during installation.
But I think you mean how do you change the blockchain folder?

First of all, the blockchain folder for Pascal Coin is not like all other coins. My folder is only 900MB. So doesn't take much space. Read whitepaper...

But to move it, is a command line "magic" :p BACKUP YOUR KEYS FIRST! I take no responsibilites!
I have moved it myself, I hate having cryptocoins in the hidden appdata, just to be sure my wallets aren't gone if I reformat (yes I do have backups as well).

Find the 'PascalCoin' folder in C:\Users\<username>\AppData\Roaming\
Move this where you like it stored, for this example, lets use D:\BLOCKCHAINS\, so you would have D:\BLOCKCHAINS\PascalCoin

Then, open a command prompt as administrator and type:

mklink /D C:\Users\<username>\AppData\Roaming\PascalCoin D:\BLOCKCHAINS\PascalCoin

Replace <username> with your username of course.. so the paths are correct. Now any app looking for the content of C:\Users\<username>\AppData\Roaming\PascalCoin will think it's there, but it's just a symlink to D:\BLOCKCHAINS\PascalCoin

Is there a way to move the data folder (C:\Users\<user>\AppData\Roaming\Peerplays core)?
Except with "mklink /d"

And how do I backup my wallet?

I think this coin needs to rebrand. Coinmarketcap seems not to want to add it due to the fact that most people immediately associate it with the scammy pozni scheme mentioned before. Call it Two Coin for what I care, but seriously..to be considered to be added to bigger exchanges etc this needs to happen and is probably the easiest thing to do as a community in regards of further development of the project. Don't count on Kim to move this, it's up to us really, but perhaps there isn't enough will and resources to contribute since there are like 3 or 4 people mining it.
