FileBaseName["F:\\2016-02-23\\11.5_mm_fan_off_pumps_off_1500_hz_3793_\
images_2048_1472_pixels_20160223_1649_time_part"]

should give the base folder name:

"11.5_mm_fan_off_pumps_off_1500_hz_3793_images_2048_1472_pixels_20160223_1649_time_part"

but due to the dot after 11 the result is:

"11"

How can I solve that?

  • $\begingroup$ It looks like you are looking for FileNameTake, not FileBaseName. FileBaseName does what it's supposed to here: it removes the extension, i.e. everything after the last dot. Note that directories can have extensions too, see e.g. .app on OS X. $\endgroup$

    $\begingroup$ @Kuba Actually the -1 is not needed. It always takes the last element of the path, whether that is a directory or not. $\endgroup$

The purpose of FileBaseName is not to take the last element of the path. It's purpose is to remove the file extension, i.e. everything after the last dot in the name. Directories can have extensions too, see e.g. .app on OS X. In your example FileBaseName is working correctly and doing what it should.

If you want to take the last element of the path, use FileNameTake.
