Using zip('test', 'data.txt') Cannot open file "data.txt" for reading

Hi,

Just recently ugraded from Matlab 2018 to 2022 togehter with change to new computer. I have a GUI that zip several data files, like data..txt and .mat with test parameter and measureing data. I can't get the zip function working again. I have even tried just do a simple text file with numeric values but when I run zip('test', 'data.txt') I get "Cannot open file "data.txt" for reading, In zip (line 75)"

zip.m line 75: archive = matlab.io.internal.archive.core.builtin.createArchive(zipFilename,{entries.file},{entries.entry},mfilename);

I have no clue what is happening, does any of you out there explain what could be the reason?

Things I have tried:

Changed regional setting sicne we in nordic contries use , instead of . as decimal

Hi, just an idea: since you are using a new computer, there may be a possibility that you do not have accurately described path for your files, or you do not have the permissions? Have you tried running Matlab as an administrator?

Thanks a lot your your replay. runt computer as Adm was a great idea and I have tried now, but same issue still.

The paths is alos something I suspceted, but it saves and load files correct expecpt that the zip functions is not working as I want.

I am 50/50 that is it some kind of computer setting or matlab is miss intrpretating the file it tries to read and zip. I have tried as method also just doing a simple .txt file with 1 2 3 in the cd but it still fails.

If any other ideas plz reach out and thanks!

Have you tried this on a different file? Not .txt but .csv or .xlsx etc.?

Thanks and I tried. I was thinking more what you mentioned run as Adm. It worked for a while but stopped workning, which made thinking about about the path. SO I copied all from domument folder (that is synced and regulary backed up) direclty to C\ instead and it worked.

Thanks a lot!
