recently i’ve installed xibo latest version(1.7.3).default value for library is only 639.k for this version.it is not sufficient for uploading the contents.so how to increase the library size?

Deephi, you are working on localhost or server on the internet? to increase the upload space you must change in php.ini

certainly the following items:

upload_max_size
post_max_size
max_execution_time
