How to Load multiple Photoshop shapes files in one go into Photoshop (super quick time saving tip) tutorial
Select a selection of shape files CSH in a folder
Drag into the Photoshop application
You can load multiple shapes sets by two methods (there are probably others)
Select a number of CSH files
Drag from the folder into the Photoshop application
OR
Select a number of Photoshop CSH files
Right click
Select open command or open with command (if you have multiple versions of Photoshop)
Now go to the panel and you will see all the items loaded, you can, of course, just load them multiple times so you could have 10 sets of the dogs added but what point would there be for that.
Select the custom shapes tool in Photoshop
Go to the custom shapes presets picker at the top of Photoshop
Open the presets picker
Select a shape
Once you have loaded all the items you want from the CSH files, you can always select them and delete them.
Select the custom shape CSH tool and then go to the panel and select the items you don't want then right click and select the delete command or hold the ALT key down.
Once you have all the items as required then you can go to the right side menu of the panel and select the save command and the CSH will be saved to the current version's format.
Select the custom shapes tool
Go to the shapes presets picker
Delete all the shapes you no longer want (right click and delete etc)
Go to the right side menu
Go to the save shapes command
Save the set as a CSH file
This approach may work with some versions of Photoshop
File menu in Photoshop
Open
Select a number of CSH files etc
Open
Please note, in some cases only one file may open and in some cases, many will open
With more recenrt versions you can now quickly bring in multiple shapes via the import command and this can be found via the window menu and shapes and in the shapes panel go to the right side menu and to the import command and then browse for the shapes files (CSH format) and select them and then import. Once loaded you will see them as groups in the shapes panel and then you can use them with the shapes tool as well as drag the designs for use as a layers. See a video at the top of the page about this.
