  We present here AMUSING\textrm{++}; the largest compilation of nearby
galaxies observed with the MUSE integral field spectrograph so far. This
collection consists of 635 galaxies from different MUSE projects covering the
redshift interval $0.0002<z<0.1$. The sample and its main properties are
characterized and described in here. It includes galaxies of almost all
morphological types, with a good coverage in the color-magnitude diagram,
within the stellar mass range between 10$^8$ to 10$^{12}$M$_\odot$, and with
properties resembling those of a diameter-selected sample. The AMUSING++ sample
is therefore suitable to study, with unprecendent detail, the properties of
nearby galaxies at global and local scales, providing us with more than 50
million individual spectra. We use this compilation to investigate the presence
of galactic outflows. We exploit the use of combined emission-line images to
explore the shape of the different ionized components and the distribution
along classical diagnostic diagrams to disentangle the different ionizing
sources across the optical extension of each galaxy. We use the cross
correlation function to estimate the level of symmetry of the emission lines as
an indication of the presence of shocks and/or active galactic nuclei. We
uncovered a total of 54 outflows, comprising $\sim$8\% of the sample. A large
number of the discovered outflows correspond to those driven by active galactic
nuclei ($\sim$60\%), suggesting some bias in the selection of our sample. No
clear evidence was found that outflow host galaxies are highly star-forming,
and outflows appear to be found within all galaxies around the star formation
sequence.
