## 5. How to remove existed bit file if storage is full

Due to the limitation of the storage, we could not copy all bit file into the miner. So if the storage is full, need to remove existed bit file when update image.

a. extract the compressed image file, like upgrade\_altcoin\_F1\_0xbtc.gz.tar

b. open runme.sh

c. add below commands:

rm –rf /fpgabit/deleteFile.conf

&#x20; rm –rf /fpgabit/deleteFile.bit

d. re-create upgrade\_altcoin\_F1\_0xbtc.gz.tar

If you only have windows, you could do it by winscp:

a.download and install winscp (winscp download link: <https://winscp.net/eng/download.php> )

b.connect to the miner by winscp

1. choose the protocol: SCP
2. input the ip of the miner
3. username: root password: root
4. click login![1111.png](https://hashaltcoin.zendesk.com/hc/article_attachments/360015569072/1111.png)
5. browse into the path: /fpagbit
6. delete the algorithm which you want to delete, take 0xbtc as an example    delete cgminer\_0xbtc.confg and fpgaminer\_top\_0xbtc.bit
