Error code 13 is caused due to storage permission issue,
There are two causes for this error:
1. Storage Permission not granted by user
2. User Updated app from Website version to google playstore version
Storage Permission not granted by user: If the user didn’t grant the storage permission to app and try to download something then this error code 13 will be shown, So you need to provide storage permission to avoid this error
Note: For Android-11 and above for Google Play store version no additional storage permission is needed, so no need check for permission, However for Website version & other than Google Playstore versions storage permissions is needed, so you need to check the storage permission status.
User Updated app from Website version to Google Playstore version: If the user installed the app from our official website and later user updated the app via Google Playstore or may Google Playstore auto updated the app, then you may get this Error code 13, This is because website version contains full storage permission(which can write, read, overwrite ,replace any file/folder across almost all locations including external storage(SD Card’s ,Pendrives) while Google Playstore version contains only limited storage permission (write & read only, no replace & overwrite permissions) due to Google Playstore policies, Means Google Playstore version cannot overwrite or replace already existing or partially existing file/folder(means partially download file/movie), So once the app changed from full permission to limited permission android will not remember that previous downloaded movie is downloaded from the same app and assumes it is created by some other app, So with the limited storage permission now app can’t continue the download of the file/movie,
And also as said above while you previously using full permission version you had selected the other than ‘Downloads’ folder which can be used by website version but later in Google Playstore version due to limited storage permission app can only write in ‘Downloads’ folder only other folder’s can’t get write permission
For this to overcome you have three options,
1. Again update the app to website version: You need to download and update the 
Torrent Pro app from our official website https://torrentpro.qinfro.com which contains full storage permission so it overwrite the file/movie which is already continues, so there will be no error, But remember this time you need to turnoff auto update of Torrent Pro app in Google Playstore so it won’t update to limited permission version again.
2. Delete the file/folder/movie from the location: You need to delete the partially downloaded file or already created folder from that location in phone file manager, so app don’t need to overwrite instead now it will write it’s own file there so there will be no error code 13.
3. Change download location: As said above if other than ‘Download’ folder is selected while using full permission website version and after updating to the Google Playstore version then due to limited permissions it can’t access other than ‘Downloads’ folder, so you will get this error code 13, so you need to change download location to ‘Downloads’ or it’s sub folders then error can be fixed.
