Extract the last version name of a folder as a text string

[Enrique.ts (Enrique)]

Hi, I’m very new to RPA uipath world, hope you can help me, I would like to extract the most current folder name “app-XX.XX.X” from the directory.

Name Modification date
app-20.10.1 21/10/2020

app-20.10.2 26/10/2020 <—

Hello @Enrique.ts and welcome to the UiPath Community forums

Once you have folder name into a string variable:
app-20.10.1 21/10/2020

And you would like to obtain the date, you can use a “Matches” activity.
Pattern:
\d{2}/\d{2}/20\d{2}
Preview the result here on Regex101.com

The result will be an ienumerable and to convert to string use an assign activity:
MATCHESOUTPUTVARIABLE(0).tostring = string.variable

Update capital letters above with Matches activity “Result”.

Hi Steven, thanks for your comment, I wanted to clarify that the date is not part of the folder name, as it shows you in this image

C:\Users\ -myname- \AppData\Local\UiPath\app-20.10.2

With your answer do you think I could use it to get the folder with the newest version “app-XX.XX.X” from the directory?

I require a process that detects the latest version of UiPath installed.

@Enrique.ts
Prototyping it with short values:

the last app entry can be found with a Regex, Linq Combination:

(From x In arrNames
Where Regex.IsMatch(x,"(?<=app-)\d{2}.\d{2}.\d{1,2}\b")
Let m = Regex.Match(x,"(?<=app-)(\d{2}).(\d{2}).(\d{1,2})\b")
Order By CInt(m.Groups(1).Value),CInt(m.Groups(2).Value),CInt(m.Groups(3).Value)
Select x).Last

Thanks to both of you @ppr @Steven_McKeering, your comments were very helpful to me, but
@ppr response using Regex was what I used since it gives me the entire path where the folder is located and of course the most important thing is that it gives me the latest version
