hi pfrank users.. i have large library of .wav files that need to be transferred to an akai mpc1000 sampler.. the filename length limit on this sampler is 16 characters.. however most of my filenames are much longer..
with most of my samples the filename is formatted like this:

nameofsampleorigin-briefsampledescription12.wav

i would like to keep only the first 3 characters of "nameofsampleorigin" field and keep a hyphen "-" and then keep the first 10 characters of "briefsampledescription" and then the last 2 characters (which are usually numbers).. resulting in:

nam-briefsampl12.wav


this sounds like a complex regex and been having troubles trying to figure it out on my own.. was hoping someone could help as to how i could do this.. thank you

Hi,

One regex will do it - for this case it's all about grouping.
Enter the following data into the custom renaming creator (do not include the single quotes):

Row: 1
Search: '^(.{3,3})(.*?)-(.{10,10})(.*?)(..)[.]wav$'
Replace: '\1-\3\5.wav'


The search expression defines 5 groups. 3 of the groups are used in the replace expression.

Hope that helps. If you need more assistance, then let me know.

Cheers,

Peter.
