What is the Size of Disavow link file?
 

I want to submit disavow links to Google, is there any size specified for the tool file size that i submit to Google for “Disavow Links”.

There is no file need to submit in disavow tool. Just sign in with your google webmaster accout, select the website which links you wanted to remove. Just be careful once the link is remove then there no procedure to come in back

There is no limit to submit it, but you have thing twice before you submit, if you doesn't know that you site has spam links better don't submit disavow link file.
