TC OOM when searching for duplicate files on large partition

Post by *Vlad » 2010-06-14, 14:13 UTC

I know I was pushing TC over the limits, but maybe you'll be interested in this OOM (Out Of Memory). I was trying to recover some files from a dying HDD over the network, and due to some quirks either in the recovery software or in the way NTFS works, the recovery created several layers of folders with some files repeated over and over. Don't ask me why, but I wanted to find out the identical files and folders, so I launched a search for such files and folders on a couple of partitions of 700 GB in size. While searching (it hasn't reach the percent phase where it looked for identical items) it displayed the following error:
---------------------------
Total Commander 7.50a fin

Out of memory.

Please report this error to the Author, with a description

Thanks for your report. It looks like you got into some kind of infinite loop in the search function: Address 577009 is in function "searchdir" which calls itself recursively.
