-----------------------------------
Summary: iOS file-transfer plugin fails to upload large files (>
200MB)
Key: CB-5790
URL: https://issues.apache.org/jira/browse/CB-5790
Project: Apache Cordova
Issue Type: Bug
Components: iOS, Plugin File Transfer
Affects Versions: 3.3.0
Environment: iOS 7.0.4 on an non retina iPad mini and an iPad 3.
Plugin v0.4.0
Reporter: Nicolas Leclerc
While trying to upload large video files (> 200MB) using the file-transfer
plugin upload function, i get a FILE_NOT_FOUND_ERR error.
Turns out the real error is as follows:

Error opening file

NSUnderlyingError=0x176cbac0 "The operation couldn’t be completed. *Cannot

Smaller files work fine so it would seem that the whole content of the file is
read into memory before uploading despite using the
{{NSDataReadingMappedIfSafe}} option of NSData.
I did find some reference to the fact that ios is indeed buffering the whole
file into memory:
